DESCRIPTION
     less is a program similar to the traditional more(1), but which allows
     backward movement in the file as well as forward movement.	 Also, less
     does not have to read the entire input file before starting, so with
     large input files it starts up faster than text editors like vi(1).  less
     uses termcap (or terminfo on some systems), so it can run on a variety of
     terminals.	 There is even limited support for hardcopy terminals.	(On a
     hardcopy terminal, lines which should be printed at the top of the screen
     are prefixed with a caret.)

     This version of less also acts as more(1) if it is called as more.	 In
     this mode, the differences are in the prompt and that more exits by
     default when it gets to the end of the file.  Commands are based on both
     traditional more and vi(1).  Commands may be preceded by a decimal
     number, called N in the descriptions below.  The number is used by some
     commands, as indicated.

COMMANDS
     In the following descriptions, ^X means control-X.	 ESC stands for the
     ESCAPE key; for example ESC-v means the two character sequence "ESCAPE",
     then "v".

     h | H
	   Help: display a summary of these commands.  If you forget all the
	   other commands, remember this one.

     SPACE | ^V | f | ^F
	   Scroll forward N lines, default one window (see option -z below).
	   If N is more than the screen size, only the final screenful is
	   displayed.  Warning: some systems use ^V as a special
	   literalization character.

     z	   Like SPACE, but if N is specified, it becomes the new window size.

     ESC-SPACE
	   Like SPACE, but scrolls a full screensful, even if it reaches end-
	   of-file in the process.

     RETURN | ^N | e | ^E | j | ^J
	   Scroll forward N lines, default 1.  The entire N lines are
	   displayed, even if N is more than the screen size.

     d | ^D
	   Scroll forward N lines, default one half of the screen size.	 If N
	   is specified, it becomes the new default for subsequent d and u
	   commands.

     b | ^B | ESC-v
	   Scroll backward N lines, default one window (see option -z below).
	   If N is more than the screen size, only the final screenful is
	   displayed.

     w	   Like ESC-v, but if N is specified, it becomes the new window size.

     y | ^Y | ^P | k | ^K
	   Scroll backward N lines, default 1.	The entire N lines are
	   displayed, even if N is more than the screen size.  Warning: some
	   systems use ^Y as a special job control character.

     u | ^U
	   Scroll backward N lines, default one half of the screen size.  If N
	   is specified, it becomes the new default for subsequent d and u
	   commands.

     ESC-) | RIGHTARROW
	   Scroll horizontally right N characters, default half the screen
	   width (see the -# option).  If a number N is specified, it becomes
	   the default for future RIGHTARROW and LEFTARROW commands.  While
	   the text is scrolled, it acts as though the -S option (chop lines)
	   were in effect.

     ESC-( | LEFTARROW
	   Scroll horizontally left N characters, default half the screen
	   width (see the -# option).  If a number N is specified, it becomes
	   the default for future RIGHTARROW and LEFTARROW commands.

     r | ^R | ^L
	   Repaint the screen.

     R	   Repaint the screen, discarding any buffered input.  Useful if the
	   file is changing while it is being viewed.

     F	   Scroll forward, and keep trying to read when the end of file is
	   reached.  Normally this command would be used when already at the
	   end of the file.  It is a way to monitor the tail of a file which
	   is growing while it is being viewed.	 (The behavior is similar to
	   the "tail -f" command.)

     g | < | ESC-<
	   Go to line N in the file, default 1 (beginning of file).  (Warning:
	   this may be slow if N is large.)

     G | > | ESC->
	   Go to line N in the file, default the end of the file.  (Warning:
	   this may be slow if N is large, or if N is not specified and
	   standard input, rather than a file, is being read.)

     p | %
	   Go to a position N percent into the file.  N should be between 0
	   and 100.

     {	   If a left curly bracket appears in the top line displayed on the
	   screen, the { command will go to the matching right curly bracket.
	   The matching right curly bracket is positioned on the bottom line
	   of the screen.  If there is more than one left curly bracket on the
	   top line, a number N may be used to specify the N-th bracket on the
	   line.

     }	   If a right curly bracket appears in the bottom line displayed on
	   the screen, the } command will go to the matching left curly
	   bracket.  The matching left curly bracket is positioned on the top
	   line of the screen.	If there is more than one right curly bracket
	   on the top line, a number N may be used to specify the N-th bracket
	   on the line.

     (	   Like {, but applies to parentheses rather than curly brackets.

     )	   Like }, but applies to parentheses rather than curly brackets.

     [	   Like {, but applies to square brackets rather than curly brackets.

     ]	   Like }, but applies to square brackets rather than curly brackets.

     ESC-^F
	   Followed by two characters, acts like {, but uses the two
	   characters as open and close brackets, respectively.	 For example,
	   "ESC ^F < >" could be used to go forward to the > which matches the
	   < in the top displayed line.

     ESC-^B
	   Followed by two characters, acts like }, but uses the two
	   characters as open and close brackets, respectively.	 For example,
	   "ESC ^B < >" could be used to go backward to the < which matches
	   the > in the bottom displayed line.

     m	   Followed by any lowercase letter, marks the current position with
	   that letter.

     '	   (Single quote.)  Followed by any lowercase letter, returns to the
	   position which was previously marked with that letter.  Followed by
	   another single quote, returns to the position at which the last
	   "large" movement command was executed.  Followed by a ^ or $, jumps
	   to the beginning or end of the file respectively.  Marks are
	   preserved when a new file is examined, so the ' command can be used
	   to switch between input files.

     ^X^X  Same as single quote.

     /pattern
	   Search forward in the file for the N-th line containing the
	   pattern.  N defaults to 1.  The pattern is a regular expression, as
	   recognized by ed(1).	 The search starts at the second line
	   displayed (but see the -a and -j options, which change this).

	   Certain characters are special if entered at the beginning of the
	   pattern; they modify the type of search rather than become part of
	   the pattern:

	   ^N | !  Search for lines which do NOT match the pattern.

	   ^E | *  Search multiple files.  That is, if the search reaches the
		   END of the current file without finding a match, the search
		   continues in the next file in the command line list.

	   ^F | @  Begin the search at the first line of the FIRST file in the
		   command line list, regardless of what is currently
		   displayed on the screen or the settings of the -a or -j
		   options.

	   ^K	   Highlight any text which matches the pattern on the current
		   screen, but don't move to the first match (KEEP current
		   position).

	   ^R	   Don't interpret regular expression metacharacters; that is,
		   do a simple textual comparison.

     ?pattern
	   Search backward in the file for the N-th line containing the
	   pattern.  The search starts at the line immediately before the top
	   line displayed.

	   Certain characters are special, as in the / command:

	   ^N | !  Search for lines which do NOT match the pattern.

	   ^E | *  Search multiple files.  That is, if the search reaches the
		   beginning of the current file without finding a match, the
		   search continues in the previous file in the command line
		   list.

	   ^F | @  Begin the search at the last line of the last file in the
		   command line list, regardless of what is currently
		   displayed on the screen or the settings of the -a or -j
		   options.

	   ^K	   As in forward searches.

	   ^R	   As in forward searches.

     ESC-/pattern
	   Same as "/*".

     ESC-?pattern
	   Same as "?*".

     n	   Repeat previous search, for N-th line containing the last pattern.
	   If the previous search was modified by ^N, the search is made for
	   the N-th line NOT containing the pattern.  If the previous search
	   was modified by ^E, the search continues in the next (or previous)
	   file if not satisfied in the current file.  If the previous search
	   was modified by ^R, the search is done without using regular
	   expressions.	 There is no effect if the previous search was
	   modified by ^F or ^K.

     N	   Repeat previous search, but in the reverse direction.

     ESC-n
	   Repeat previous search, but crossing file boundaries.  The effect
	   is as if the previous search were modified by *.

     ESC-N
	   Repeat previous search, but in the reverse direction and crossing
	   file boundaries.

     ESC-u
	   Undo search highlighting.  Turn off highlighting of strings
	   matching the current search pattern.	 If highlighting is already
	   off because of a previous ESC-u command, turn highlighting back on.
	   Any search command will also turn highlighting back on.
	   (Highlighting can also be disabled by toggling the -G option; in
	   that case search commands do not turn highlighting back on.)

     :e [filename]
	   Examine a new file.	If the filename is missing, the "current" file
	   (see the :n and :p commands below) from the list of files in the
	   command line is re-examined.	 A percent sign (%) in the filename is
	   replaced by the name of the current file.  A pound sign (#) is
	   replaced by the name of the previously examined file.  However, two
	   consecutive percent signs are simply replaced with a single percent
	   sign.  This allows you to enter a filename that contains a percent
	   sign in the name.  Similarly, two consecutive pound signs are
	   replaced with a single pound sign.  The filename is inserted into
	   the command line list of files so that it can be seen by subsequent
	   :n and :p commands.	If the filename consists of several files,
	   they are all inserted into the list of files and the first one is
	   examined.  If the filename contains one or more spaces, the entire
	   filename should be enclosed in double quotes (also see the -"
	   option).

     ^X^V | E
	   Same as :e.	Warning: some systems use ^V as a special
	   literalization character.  On such systems, you may not be able to
	   use ^V.

     :n	   Examine the next file (from the list of files given in the command
	   line).  If a number N is specified, the N-th next file is examined.

     :p	   Examine the previous file in the command line list.	If a number N
	   is specified, the N-th previous file is examined.

     :t	   Go to the specified tag.

     :x	   Examine the first file in the command line list.  If a number N is
	   specified, the N-th file in the list is examined.

     :d	   Remove the current file from the list of files.

     t	   Go to the next tag, if there were more than one matches for the
	   current tag.	 See the -t option for more details about tags.

     T	   Go to the previous tag, if there were more than one matches for the
	   current tag.

     = | ^G | :f
	   Prints some information about the file being viewed, including its
	   name and the line number and byte offset of the bottom line being
	   displayed.  If possible, it also prints the length of the file, the
	   number of lines in the file and the percent of the file above the
	   last displayed line.

     -	   Followed by one of the command line option letters (see OPTIONS
	   below), this will change the setting of that option and print a
	   message describing the new setting.	If a ^P (CONTROL-P) is entered
	   immediately after the dash, the setting of the option is changed
	   but no message is printed.  If the option letter has a numeric
	   value (such as -b or -h), or a string value (such as -P or -t), a
	   new value may be entered after the option letter.  If no new value
	   is entered, a message describing the current setting is printed and
	   nothing is changed.

     --	   Like the - command, but takes a long option name (see OPTIONS
	   below) rather than a single option letter.  You must press RETURN
	   after typing the option name.  A ^P immediately after the second
	   dash suppresses printing of a message describing the new setting,
	   as in the - command.

     -+	   Followed by one of the command line option letters this will reset
	   the option to its default setting and print a message describing
	   the new setting.  (The "-+X" command does the same thing as "-+X"
	   on the command line.)  This does not work for string-valued
	   options.

     --+   Like the -+ command, but takes a long option name rather than a
	   single option letter.

     -!	   Followed by one of the command line option letters, this will reset
	   the option to the "opposite" of its default setting and print a
	   message describing the new setting.	This does not work for numeric
	   or string-valued options.

     --!   Like the -! command, but takes a long option name rather than a
	   single option letter.

     _	   (Underscore.)  Followed by one of the command line option letters,
	   this will print a message describing the current setting of that
	   option.  The setting of the option is not changed.

     __	   (Double underscore.)	 Like the _ (underscore) command, but takes a
	   long option name rather than a single option letter.	 You must
	   press RETURN after typing the option name.

     +cmd  Causes the specified cmd to be executed each time a new file is
	   examined.  For example, +G causes less to initially display each
	   file starting at the end rather than the beginning.

     V	   Prints the version number of less being run.

     q | Q | :q | :Q | ZZ
	   Exits less.

     The following four commands may or may not be valid, depending on your
     particular installation.

     v	   Invokes an editor to edit the current file being viewed.  The
	   editor is taken from the environment variable VISUAL, if defined,
	   or EDITOR if VISUAL is not defined, or defaults to "vi" if neither
	   VISUAL nor EDITOR is defined.  See also the discussion of LESSEDIT
	   under the section on PROMPTS below.

     ! shell-command
	   Invokes a shell to run the shell-command given.  A percent sign (%)
	   in the command is replaced by the name of the current file.	A
	   pound sign (#) is replaced by the name of the previously examined
	   file.  "!!" repeats the last shell command.	"!" with no shell
	   command simply invokes a shell.  The shell is taken from the
	   environment variable SHELL, or defaults to "sh".

     | <m> shell-command
	   <m> represents any mark letter.  Pipes a section of the input file
	   to the given shell command.	The section of the file to be piped is
	   between the first line on the current screen and the position
	   marked by the letter.  <m> may also be ^ or $ to indicate beginning
	   or end of file respectively.	 If <m> is . or newline, the current
	   screen is piped.

     s filename
	   Save the input to a file.  This only works if the input is a pipe,
	   not an ordinary file.

OPTIONS
     Command line options are described below.	Most options may be changed
     while less is running, via the "-" command.

     Most options may be given in one of two forms: either a dash followed by
     a single letter, or two dashes followed by a long option name.  A long
     option name may be abbreviated as long as the abbreviation is
     unambiguous.  For example, --quit-at-eof may be abbreviated --quit, but
     not --qui, since both --quit-at-eof and --quiet begin with --qui.	Some
     long option names are in uppercase, such as --QUIT-AT-EOF, as distinct
     from --quit-at-eof.  Such option names need only have their first letter
     capitalized; the remainder of the name may be in either case.  For
     example, --Quit-at-eof is equivalent to --QUIT-AT-EOF.

     Options are also taken from the environment variable LESS if the command
     is less, or from the environment variable MORE if the command is more.
     For example, to avoid typing "less -options ..." each time less is
     invoked, you might tell csh(1):

	   setenv LESS -options

     or if you use sh(1):

	   LESS="-options"; export LESS

     The environment variable is parsed before the command line, so command
     line options override the LESS environment variable.  If an option
     appears in the LESS variable, it can be reset to its default value on the
     command line by beginning the command line option with "-+".

     For options like -P which take a following string, a dollar sign ($) must
     be used to signal the end of the string.  For example, to separate a
     prompt value from any other options with dollar sign between them:

	   LESS="-Ps--More--$-C -e"

     -? | --help
	   This option displays a summary of the commands accepted by less
	   (the same as the h command).	 (Depending on how your shell
	   interprets the question mark, it may be necessary to quote the
	   question mark, thus: "-\?".)

     -a | --search-skip-screen
	   Causes searches to start after the last line displayed on the
	   screen, thus skipping all lines displayed on the screen.  By
	   default, searches start at the second line on the screen (or after
	   the last found line; see the -j option).

     -B | --auto-buffers
	   By default, when data is read from a pipe, buffers are allocated
	   automatically as needed.  If a large amount of data is read from
	   the pipe, this can cause a large amount of memory to be allocated.
	   The -B option disables this automatic allocation of buffers for
	   pipes, so that only 64K (or the amount of space specified by the -b
	   option) is used for the pipe.  Warning: use of -B can result in
	   erroneous display, since only the most recently viewed part of the
	   file is kept in memory; any earlier data is lost.

     -bn | --buffers=n
	   Specifies the amount of buffer space less will use for each file,
	   in units of kilobytes (1024 bytes).	By default 64K of buffer space
	   is used for each file (unless the file is a pipe; see the -B
	   option).  The -b option specifies instead that n kilobytes of
	   buffer space should be used for each file.  If n is -1, buffer
	   space is unlimited; that is, the entire file is read into memory.

     -C | --CLEAR-SCREEN
	   The -C option is like -c, but the screen is cleared before it is
	   repainted.

     -c | --clear-screen
	   Causes full screen repaints to be painted from the top line down.
	   By default, full screen repaints are done by scrolling from the
	   bottom of the screen.

     -d | --dumb (less only)
	   The -d option suppresses the error message normally displayed if
	   the terminal is dumb; that is, lacks some important capability,
	   such as the ability to clear the screen or scroll backward.	The -d
	   option does not otherwise change the behavior of less on a dumb
	   terminal.  This option is on by default when invoked as more.

     -d (more only)
	   The -d option causes the default prompt to include the basic
	   directions ``[Press space to continue, 'q' to quit.]''.  The -d
	   option also causes the message ``[Press 'h' for instructions.]'' to
	   be displayed when an invalid command is entered (normally, the bell
	   is rung).  This option is useful in environments where users may
	   not be experienced with pagers.

     -E | --QUIT-AT-EOF
	   Causes less to automatically exit the first time it reaches end-of-
	   file.

     -e | --quit-at-eof
	   Causes less to automatically exit the second time it reaches end-
	   of-file.  By default, the only way to exit less is via the "q"
	   command.

     -F | --quit-if-one-screen
	   Causes less to automatically exit if the entire file can be
	   displayed on the first screen.

     -f | --force
	   Forces non-regular files to be opened.  (A non-regular file is a
	   directory or a device special file.)	 Also suppresses the warning
	   message when a binary file is opened.  By default, less will refuse
	   to open non-regular files.

     -G | --HILITE-SEARCH
	   The -G option suppresses all highlighting of strings found by
	   search commands.

     -g | --hilite-search
	   Normally, less will highlight ALL strings which match the last
	   search command.  The -g option changes this behavior to highlight
	   only the particular string which was found by the last search
	   command.  This can cause less to run somewhat faster than the
	   default.

     -hn | --max-back-scroll=n
	   Specifies a maximum number of lines to scroll backward.  If it is
	   necessary to scroll backward more than n lines, the screen is
	   repainted in a forward direction instead.  (If the terminal does
	   not have the ability to scroll backward, -h0 is implied.)

     -I | --IGNORE-CASE
	   Like -i, but searches ignore case even if the pattern contains
	   uppercase letters.

     -i | --ignore-case
	   Causes searches to ignore case; that is, uppercase and lowercase
	   are considered identical.  This option is ignored if any uppercase
	   letters appear in the search pattern; in other words, if a pattern
	   contains uppercase letters, then that search does not ignore case.

     -J | --status-column
	   Displays a status column at the left edge of the screen.  The
	   status column shows the lines that matched the current search.  The
	   status column is also used if the -w or -W option is in effect.

     -jn | --jump-target=n
	   Specifies a line on the screen where the "target" line is to be
	   positioned.	A target line is the object of a text search, tag
	   search, jump to a line number, jump to a file percentage, or jump
	   to a marked position.  The screen line is specified by a number:
	   the top line on the screen is 1, the next is 2, and so on.  The
	   number may be negative to specify a line relative to the bottom of
	   the screen: the bottom line on the screen is -1, the second to the
	   bottom is -2, and so on.  If the -j option is used, searches begin
	   at the line immediately after the target line.  For example, if "-
	   j4" is used, the target line is the fourth line on the screen, so
	   searches begin at the fifth line on the screen.

     -kfilename | --lesskey-file=filename
	   Causes less to open and interpret the named file as a lesskey(1)
	   file.  Multiple -k options may be specified.	 If the LESSKEY or
	   LESSKEY_SYSTEM environment variable is set, or if a lesskey file is
	   found in a standard place (see KEY BINDINGS), it is also used as a
	   lesskey file.

     -L | --no-lessopen
	   Ignore the LESSOPEN environment variable (see the INPUT
	   PREPROCESSOR section below).	 This option can be set from within
	   less, but it will apply only to files opened subsequently, not to
	   the file which is currently open.  When invoked as more, the
	   LESSOPEN environment variable is ignored by default.

     -M | --LONG-PROMPT
	   Causes less to prompt even more verbosely than more.

     -m | --long-prompt
	   Causes less to prompt verbosely (like more), with the percent into
	   the file.  By default, less prompts with a colon.

     -N | --LINE-NUMBERS
	   Causes a line number to be displayed at the beginning of each line
	   in the display.

     -n | --line-numbers
	   Suppresses line numbers.  The default (to use line numbers) may
	   cause less to run more slowly in some cases, especially with a very
	   large input file.  Suppressing line numbers with the -n option will
	   avoid this problem.	Using line numbers means: the line number will
	   be displayed in the verbose prompt and in the = command, and the v
	   command will pass the current line number to the editor (see also
	   the discussion of LESSEDIT in PROMPTS below).

     -Ofilename | --LOG-FILE=filename
	   The -O option is like -o, but it will overwrite an existing file
	   without asking for confirmation.

	   If no log file has been specified, the -o and -O options can be
	   used from within less to specify a log file.	 Without a file name,
	   they will simply report the name of the log file.  The "s" command
	   is equivalent to specifying -o from within less.

     -ofilename | --log-file=filename
	   Causes less to copy its input to the named file as it is being
	   viewed.  This applies only when the input file is a pipe, not an
	   ordinary file.  If the file already exists, less will ask for
	   confirmation before overwriting it.

     -Pprompt | --prompt=prompt
	   Provides a way to tailor the three prompt styles to your own
	   preference.	This option would normally be put in the LESS
	   environment variable, rather than being typed in with each less
	   command.  Such an option must either be the last option in the LESS
	   variable, or be terminated by a dollar sign.	 -Ps followed by a
	   string changes the default (short) prompt to that string.  -Pm
	   changes the medium (-m) prompt.  -PM changes the long (-M) prompt.
	   -Ph changes the prompt for the help screen.	-P= changes the
	   message printed by the = command.  -Pw changes the message printed
	   while waiting for data (in the F command).  All prompt strings
	   consist of a sequence of letters and special escape sequences.  See
	   the section on PROMPTS for more details.

     -ppattern | --pattern=pattern
	   The -p option on the command line is equivalent to specifying
	   +/pattern; that is, it tells less to start at the first occurrence
	   of pattern in the file.

     -Q | --QUIET | --SILENT
	   Causes totally "quiet" operation: the terminal bell is never rung.

     -q | --quiet | --silent
	   Causes moderately "quiet" operation: the terminal bell is not rung
	   if an attempt is made to scroll past the end of the file or before
	   the beginning of the file.  If the terminal has a "visual bell", it
	   is used instead.  The bell will be rung on certain other errors,
	   such as typing an invalid character.	 The default is to ring the
	   terminal bell in all such cases.

     -R | --RAW-CONTROL-CHARS
	   Like -r, but tries to keep track of the screen appearance where
	   possible.  This works only if the input consists of normal text and
	   possibly some ANSI "color" escape sequences, which are sequences of
	   the form:

		 ESC [ ... m

	   where the "..." is zero or more characters other than "m".  For the
	   purpose of keeping track of screen appearance, all control
	   characters and all ANSI color escape sequences are assumed to not
	   move the cursor.  You can make less think that characters other
	   than "m" can end ANSI color escape sequences by setting the
	   environment variable LESSANSIENDCHARS to the list of characters
	   which can end a color escape sequence.

     -r | --raw-control-chars
	   Causes "raw" control characters to be displayed.  The default is to
	   display control characters using the caret notation; for example, a
	   control-A (octal 001) is displayed as "^A".	Warning: when the -r
	   option is used, less cannot keep track of the actual appearance of
	   the screen (since this depends on how the screen responds to each
	   type of control character).	Thus, various display problems may
	   result, such as long lines being split in the wrong place.

     -S | --chop-long-lines
	   Causes lines longer than the screen width to be chopped rather than
	   folded.  That is, the portion of a long line that does not fit in
	   the screen width is not shown.  The default is to fold long lines;
	   that is, display the remainder on the next line.

     -s | --squeeze-blank-lines
	   Causes consecutive blank lines to be squeezed into a single blank
	   line.

     -Ttagsfile | --tag-file=tagsfile
	   Specifies a tags file to be used instead of "tags".

     -ttag | --tag=tag
	   The -t option, followed immediately by a TAG, will edit the file
	   containing that tag.	 For this to work, tag information must be
	   available; for example, there may be a file in the current
	   directory called "tags", which was previously built by ctags(1) or
	   an equivalent command.  If the environment variable LESSGLOBALTAGS
	   is set, it is taken to be the name of a command compatible with
	   global, and that command is executed to find the tag.  (See
	   http://www.gnu.org/software/global/global.html).  The -t option may
	   also be specified from within less (using the - command) as a way
	   of examining a new file.  The command ":t" is equivalent to
	   specifying -t from within less.

     -U | --UNDERLINE-SPECIAL
	   Causes backspaces, tabs and carriage returns to be treated as
	   control characters; that is, they are handled as specified by the
	   -r option.

	   By default, if neither -u nor -U is given, backspaces which appear
	   adjacent to an underscore character are treated specially: the
	   underlined text is displayed using the terminal's hardware
	   underlining capability.  Also, backspaces which appear between two
	   identical characters are treated specially: the overstruck text is
	   printed using the terminal's hardware boldface capability.  Other
	   backspaces are deleted, along with the preceding character.
	   Carriage returns immediately followed by a newline are deleted.
	   Other carriage returns are handled as specified by the -r option.
	   Text which is overstruck or underlined can be searched for if
	   neither -u nor -U is in effect.

     -u | --underline-special
	   Causes backspaces and carriage returns to be treated as printable
	   characters; that is, they are sent to the terminal when they appear
	   in the input.

     -V | --version
	   Displays the version number of less.

     -W | --HILITE-UNREAD
	   Like -w, but temporarily highlights the first new line after any
	   forward movement command larger than one line.

     -w | --hilite-unread
	   Temporarily highlights the first "new" line after a forward
	   movement of a full page.  The first "new" line is the line
	   immediately following the line previously at the bottom of the
	   screen.  Also highlights the target line after a g or p command.
	   The highlight is removed at the next command which causes movement.
	   The entire line is highlighted, unless the -J option is in effect,
	   in which case only the status column is highlighted.

     -X | --no-init
	   Disables sending the termcap initialization and deinitialization
	   strings to the terminal.  This is sometimes desirable if the
	   deinitialization string does something unnecessary, like clearing
	   the screen.

     -xn,... | --tabs=n,...
	   Sets tab stops.  If only one n is specified, tab stops are set at
	   multiples of n.  If multiple values separated by commas are
	   specified, tab stops are set at those positions, and then continue
	   with the same spacing as the last two.  For example, -x9,17 will
	   set tabs at positions 9, 17, 25, 33, etc.  The default for n is 8.

     -yn | --max-forw-scroll=n
	   Specifies a maximum number of lines to scroll forward.  If it is
	   necessary to scroll forward more than n lines, the screen is
	   repainted instead.  The -c or -C option may be used to repaint from
	   the top of the screen if desired.  By default, any forward movement
	   causes scrolling.

     -[z]n | --window=n
	   Changes the default scrolling window size to n lines.  The default
	   is one screenful.  The z and w commands can also be used to change
	   the window size.  The "z" may be omitted for compatibility with
	   more.  If the number n is negative, it indicates n lines less than
	   the current screen size.  For example, if the screen is 24 lines,
	   -z-4 sets the scrolling window to 20 lines.	If the screen is
	   resized to 40 lines, the scrolling window automatically changes to
	   36 lines.

     --no-keypad
	   Disables sending the keypad initialization and deinitialization
	   strings to the terminal.  This is sometimes useful if the keypad
	   strings make the numeric keypad behave in an undesirable manner.

     -cc | --quotes=cc
	   Changes the filename quoting character.  This may be necessary if
	   you are trying to name a file which contains both spaces and quote
	   characters.	Followed by a single character, this changes the quote
	   character to that character.	 Filenames containing a space should
	   then be surrounded by that character rather than by double quotes.
	   Followed by two characters, changes the open quote to the first
	   character, and the close quote to the second character.  Filenames
	   containing a space should then be preceded by the open quote
	   character and followed by the close quote character.	 Note that
	   even after the quote characters are changed, this option remains -"
	   (a dash followed by a double quote).

     -~ | --tilde
	   Normally lines after end of file are displayed as a single tilde
	   (~).	 This option causes lines after end of file to be displayed as
	   blank lines.

     -# | --shift
	   Specifies the default number of positions to scroll horizontally in
	   the RIGHTARROW and LEFTARROW commands.  If the number specified is
	   zero, it sets the default number of positions to one half of the
	   screen width.

     --	   A command line argument of "--" marks the end of option arguments.
	   Any arguments following this are interpreted as filenames.  This
	   can be useful when viewing a file whose name begins with a "-" or
	   "+".

     +	   If a command line option begins with +, the remainder of that
	   option is taken to be an initial command to less.  For example, +G
	   tells less to start at the end of the file rather than the
	   beginning, and +/xyz tells it to start at the first occurrence of
	   "xyz" in the file.  As a special case, +<number> acts like
	   +<number>g; that is, it starts the display at the specified line
	   number (however, see the caveat under the "g" command above).  If
	   the option starts with ++, the initial command applies to every
	   file being viewed, not just the first one.  The + command described
	   previously may also be used to set (or change) an initial command
	   for every file.

LINE EDITING
     When entering command line at the bottom of the screen (for example, a
     filename for the :e command, or the pattern for a search command),
     certain keys can be used to manipulate the command line.  Most commands
     have an alternate form in [ brackets ] which can be used if a key does
     not exist on a particular keyboard.  Any of these special keys may be
     entered literally by preceding it with the "literal" character, either ^V
     or ^A.  A backslash itself may also be entered literally by entering two
     backslashes.

     LEFTARROW [ESC-h]
	     Move the cursor one space to the left.

     RIGHTARROW [ESC-l]
	     Move the cursor one space to the right.

     ^LEFTARROW [ESC-b or ESC-LEFTARROW]
	     (That is, CONTROL and LEFTARROW simultaneously.)  Move the cursor
	     one word to the left.

     ^RIGHTARROW [ESC-w or ESC-RIGHTARROW]
	     (That is, CONTROL and RIGHTARROW simultaneously.)	Move the
	     cursor one word to the right.

     HOME [ESC-0]
	     Move the cursor to the beginning of the line.

     END [ESC-$]
	     Move the cursor to the end of the line.

     BACKSPACE
	     Delete the character to the left of the cursor, or cancel the
	     command if the command line is empty.

     DELETE or [ESC-x]
	     Delete the character under the cursor.

     ^BACKSPACE [ESC-BACKSPACE]
	     (That is, CONTROL and BACKSPACE simultaneously.)  Delete the word
	     to the left of the cursor.

     ^DELETE [ESC-X or ESC-DELETE]
	     (That is, CONTROL and DELETE simultaneously.)  Delete the word
	     under the cursor.

     UPARROW [ESC-k]
	     Retrieve the previous command line.

     DOWNARROW [ESC-j]
	     Retrieve the next command line.

     TAB     Complete the partial filename to the left of the cursor.  If it
	     matches more than one filename, the first match is entered into
	     the command line.	Repeated TABs will cycle through the other
	     matching filenames.  If the completed filename is a directory, a
	     "/" is appended to the filename.  The environment variable
	     LESSSEPARATOR can be used to specify a different character to
	     append to a directory name.

     BACKTAB [ESC-TAB]
	     Like TAB, but cycles in the reverse direction through the
	     matching filenames.

     ^L	     Complete the partial filename to the left of the cursor.  If it
	     matches more than one filename, all matches are entered into the
	     command line (if they fit).

     ^U	     Delete the entire command line, or cancel the command if the
	     command line is empty.  If you have changed your line-kill
	     character to something other than ^U, that character is used
	     instead of ^U.

KEY BINDINGS
     You may define your own less commands by using the program lesskey(1) to
     create a lesskey file.  This file specifies a set of command keys and an
     action associated with each key.  You may also use lesskey to change the
     line-editing keys (see LINE EDITING), and to set environment variables.
     If the environment variable LESSKEY is set, less uses that as the name of
     the lesskey file.	Otherwise, less looks for a lesskey file called
     "$HOME/.less".  See the lesskey(1) manual page for more details.

     A system-wide lesskey file may also be set up to provide key bindings.
     If a key is defined in both a local lesskey file and in the system-wide
     file, key bindings in the local file take precedence over those in the
     system-wide file.	If the environment variable LESSKEY_SYSTEM is set,
     less uses that as the name of the system-wide lesskey file.  Otherwise,
     less looks in a standard place for the system-wide lesskey file: On
     OpenBSD, the system-wide lesskey file is /etc/sysless.

INPUT PREPROCESSOR
     You may define an "input preprocessor" for less.  Before less opens a
     file, it first gives your input preprocessor a chance to modify the way
     the contents of the file are displayed.  An input preprocessor is simply
     an executable program (or shell script), which writes the contents of the
     file to a different file, called the replacement file.  The contents of
     the replacement file are then displayed in place of the contents of the
     original file.  However, it will appear to the user as if the original
     file is opened; that is, less will display the original filename as the
     name of the current file.

     An input preprocessor receives one command line argument, the original
     filename, as entered by the user.	It should create the replacement file,
     and when finished print the name of the replacement file to its standard
     output.  If the input preprocessor does not output a replacement
     filename, less uses the original file, as normal.	The input preprocessor
     is not called when viewing standard input.	 To set up an input
     preprocessor, set the LESSOPEN environment variable to a command line
     which will invoke your input preprocessor.	 This command line should
     include one occurrence of the string "%s", which will be replaced by the
     filename when the input preprocessor command is invoked.

     When less closes a file opened in such a way, it will call another
     program, called the input postprocessor, which may perform any desired
     clean-up action (such as deleting the replacement file created by
     LESSOPEN).	 This program receives two command line arguments, the
     original filename as entered by the user, and the name of the replacement
     file.  To set up an input postprocessor, set the LESSCLOSE environment
     variable to a command line which will invoke your input postprocessor.
     It may include two occurrences of the string "%s"; the first is replaced
     with the original name of the file and the second with the name of the
     replacement file, which was output by LESSOPEN.

     For example, these two scripts will allow you to keep files in compressed
     format, but still let less view them directly:

     lessopen.sh:

	   #! /bin/sh
	   case "$1" in
	   *.Z)	   uncompress -c $1  >/tmp/less.$$  2>/dev/null
		   if [ -s /tmp/less.$$ ]; then
			   echo /tmp/less.$$
		   else
			   rm -f /tmp/less.$$
		   fi
		   ;;
	   esac

     lessclose.sh:

	   #! /bin/sh
	   rm $2

     To use these scripts, put them both where they can be executed and set
     LESSOPEN="lessopen.sh %s", and LESSCLOSE="lessclose.sh %s %s".  More
     complex LESSOPEN and LESSCLOSE scripts may be written to accept other
     types of compressed files, and so on.

     It is also possible to set up an input preprocessor to pipe the file data
     directly to less, rather than putting the data into a replacement file.
     This avoids the need to decompress the entire file before starting to
     view it.  An input preprocessor that works this way is called an input
     pipe.  An input pipe, instead of writing the name of a replacement file
     on its standard output, writes the entire contents of the replacement
     file on its standard output.  If the input pipe does not write any
     characters on its standard output, then there is no replacement file and
     less uses the original file, as normal.  To use an input pipe, make the
     first character in the LESSOPEN environment variable a vertical bar (|)
     to signify that the input preprocessor is an input pipe.

     For example, this script will work like the previous example scripts:

     lesspipe.sh:

	   #! /bin/sh
	   case "$1" in
	   *.Z)	   uncompress -c $1  2>/dev/null
		   ;;
	   esac

     To use this script, put it where it can be executed and set
     LESSOPEN="|lesspipe.sh %s".  When an input pipe is used, a LESSCLOSE
     postprocessor can be used, but it is usually not necessary since there is
     no replacement file to clean up.  In this case, the replacement file name
     passed to the LESSCLOSE postprocessor is "-".

NATIONAL CHARACTER SETS
     There are three types of characters in the input file:

     normal characters	 Can be displayed directly to the screen.

     control characters	 Should not be displayed directly, but are expected to
			 be found in ordinary text files (such as backspace
			 and tab).

     binary characters	 Should not be displayed directly and are not expected
			 to be found in text files.

     A "character set" is simply a description of which characters are to be
     considered normal, control, and binary.  The LESSCHARSET environment
     variable may be used to select a character set.  Possible values for
     LESSCHARSET are:

     ascii     BS, TAB, NL, CR, and formfeed are control characters, all chars
	       with values between 32 and 126 are normal, and all others are
	       binary.

     iso8859   Selects an ISO 8859 character set.  This is the same as ASCII,
	       except characters between 160 and 255 are treated as normal
	       characters.

     latin1    Same as iso8859.

     latin9    Same as iso8859.

     dos       Selects a character set appropriate for MS-DOS.

     ebcdic    Selects an EBCDIC character set.

     IBM-1047  Selects an EBCDIC character set used by OS/390 UNIX Services.
	       This is the EBCDIC analogue of latin1.  You get similar results
	       by setting either LESSCHARSET=IBM-1047 or LC_CTYPE=en_US in
	       your environment.

     koi8-r    Selects a Russian character set.

     next      Selects a character set appropriate for NeXT computers.

     utf-8     Selects the UTF-8 encoding of the ISO 10646 character set.

     In special cases, it may be desired to tailor less to use a character set
     other than the ones definable by LESSCHARSET.  In this case, the
     environment variable LESSCHARDEF can be used to define a character set.
     It should be set to a string where each character in the string
     represents one character in the character set.  The character "." is used
     for a normal character, "c" for control, and "b" for binary.  A decimal
     number may be used for repetition.	 For example, "bccc4b." would mean
     character 0 is binary, 1, 2 and 3 are control, 4, 5, 6 and 7 are binary,
     and 8 is normal.  All characters after the last are taken to be the same
     as the last, so characters 9 through 255 would be normal.	(This is an
     example, and does not necessarily represent any real character set.)

     This table shows the value of LESSCHARDEF which is equivalent to each of
     the possible values for LESSCHARSET:

	   ascii	   8bcccbcc18b95.b
	   dos		   8bcccbcc12bc5b95.b.
	   ebcdic	   5bc6bcc7bcc41b.9b7.9b5.b..8b6.10b6.b9.7b
			   9.8b8.17b3.3b9.7b9.8b8.6b10.b.b.b.
	   IBM-1047	   4cbcbc3b9cbccbccbb4c6bcc5b3cbbc4bc4bccbc
			   191.b
	   iso8859	   8bcccbcc18b95.33b.
	   koi8-r	   8bcccbcc18b95.b128.
	   latin1	   8bcccbcc18b95.33b.
	   next		   8bcccbcc18b95.bb125.bb

     If neither LESSCHARSET nor LESSCHARDEF is set, but the string "UTF-8" is
     found in the LC_ALL, LC_CTYPE or LANG environment variables, then the
     default character set is utf-8.

     If that string is not found, but your system supports the setlocale
     interface, less will use setlocale to determine the character set.
     setlocale is controlled by setting the LANG or LC_CTYPE environment
     variables.

     Finally, if the setlocale interface is also not available, the default
     character set is latin1.

     Control and binary characters are displayed in standout (reverse video).
     Each such character is displayed in caret notation if possible (e.g. ^A
     for control-A).  Caret notation is used only if inverting the 0100 bit
     results in a normal printable character.  Otherwise, the character is
     displayed as a hex number in angle brackets.  This format can be changed
     by setting the LESSBINFMT environment variable.  LESSBINFMT may begin
     with a "*" and one character to select the display attribute: "*k" is
     blinking, "*d" is bold, "*u" is underlined, "*s" is standout, and "*n" is
     normal.  If LESSBINFMT does not begin with a "*", normal attribute is
     assumed.  The remainder of LESSBINFMT is a string which may include one
     printf-style escape sequence (a % followed by x, X, o, d, etc.).  For
     example, if LESSBINFMT is "*u[%x]", binary characters are displayed in
     underlined hexadecimal surrounded by brackets.  The default if no
     LESSBINFMT is specified is "*s<%X>".

PROMPTS
     The -P option allows you to tailor the prompt to your preference.	The
     string given to the -P option replaces the specified prompt string.
     Certain characters in the string are interpreted specially.  The prompt
     mechanism is rather complicated to provide flexibility, but the ordinary
     user need not understand the details of constructing personalized prompt
     strings.

     A percent sign followed by a single character is expanded according to
     what the following character is:

     %bX     Replaced by the byte offset into the current input file.  The b
	     is followed by a single character (shown as X above) which
	     specifies the line whose byte offset is to be used.  If the
	     character is a "t", the byte offset of the top line in the
	     display is used, an "m" means use the middle line, a "b" means
	     use the bottom line, a "B" means use the line just after the
	     bottom line, and a "j" means use the "target" line, as specified
	     by the -j option.

     %B	     Replaced by the size of the current input file.

     %c	     Replaced by the column number of the text appearing in the first
	     column of the screen.

     %dX     Replaced by the page number of a line in the input file.  The
	     line to be used is determined by the X, as with the %b option.

     %D	     Replaced by the number of pages in the input file, or
	     equivalently, the page number of the last line in the input file.

     %E	     Replaced by the name of the editor (from the VISUAL environment
	     variable, or the EDITOR environment variable if VISUAL is not
	     defined).	See the discussion of the LESSEDIT feature below.

     %f	     Replaced by the name of the current input file.

     %i	     Replaced by the index of the current file in the list of input
	     files.

     %lX     Replaced by the line number of a line in the input file.  The
	     line to be used is determined by the X, as with the %b option.

     %L	     Replaced by the line number of the last line in the input file.

     %m	     Replaced by the total number of input files.

     %pX     Replaced by the percent into the current input file, based on
	     byte offsets.  The line used is determined by the X, as with the
	     %b option.

     %PX     Replaced by the percent into the current input file, based on
	     line numbers.  The line used is determined by the X, as with the
	     %b option.

     %s	     Same as %B.

     %t	     Causes any trailing spaces to be removed.	Usually used at the
	     end of the string, but may appear anywhere.

     %x	     Replaced by the name of the next input file in the list.

     If any item is unknown (for example, the file size if input is a pipe), a
     question mark is printed instead.

     The format of the prompt string can be changed depending on certain
     conditions.  A question mark followed by a single character acts like an
     "IF": depending on the following character, a condition is evaluated.  If
     the condition is true, any characters following the question mark and
     condition character, up to a period, are included in the prompt.  If the
     condition is false, such characters are not included.  A colon appearing
     between the question mark and the period can be used to establish an
     "ELSE": any characters between the colon and the period are included in
     the string, if and only if the IF condition is false.  Condition
     characters (which follow a question mark) may be:

     ?a	     True if any characters have been included in the prompt so far.

     ?bX     True if the byte offset of the specified line is known.

     ?B	     True if the size of the current input file is known.

     ?c	     True if the text is horizontally shifted (%c is not zero).

     ?dX     True if the page number of the specified line is known.

     ?e	     True if at end-of-file.

     ?f	     True if there is an input filename (that is, if input is not a
	     pipe).

     ?lX     True if the line number of the specified line is known.

     ?L	     True if the line number of the last line in the file is known.

     ?m	     True if there is more than one input file.

     ?n	     True if this is the first prompt in a new input file.

     ?pX     True if the percent into the current input file, based on byte
	     offsets, of the specified line is known.

     ?PX     True if the percent into the current input file, based on line
	     numbers, of the specified line is known.

     ?s	     Same as "?B".

     ?x	     True if there is a next input file (that is, if the current input
	     file is not the last one).

     Any characters other than the special ones (question mark, colon, period,
     percent, and backslash) become literally part of the prompt.  Any of the
     special characters may be included in the prompt literally by preceding
     it with a backslash.

     Some examples:

	   ?f%f:Standard input.

     This prompt prints the filename, if known; otherwise the string "Standard
     input".

	   ?f%f .?ltLine %lt:?pt%pt\%:?btByte %bt:-...

     This prompt would print the filename, if known.  The filename is followed
     by the line number, if known, otherwise the percent if known, otherwise
     the byte offset if known.	Otherwise, a dash is printed.  Notice how each
     question mark has a matching period, and how the % after the %pt is
     included literally by escaping it with a backslash.

	   ?n?f%f .?m(file %i of %m) ..?e(END) ?x- Next\: %x..%t

     This prints the filename if this is the first prompt in a file, followed
     by the "file N of N" message if there is more than one input file.	 Then,
     if we are at end-of-file, the string "(END)" is printed followed by the
     name of the next file, if there is one.  Finally, any trailing spaces are
     truncated.	 This is the default prompt.  For reference, here are the
     defaults for the other two prompts (-m and -M respectively).  Each is
     broken into two lines here for readability only.

	   ?f%f .?m(file %i of %m) .?e(END) ?x- Next\: %x.:
		   ?pB%pB\%:byte %bB?s/%s...%t

	   ?f%f .?n?m(file %i of %m) ..?ltlines %lt-%lb?L/%L. :
		   byte %bB?s/%s. .?e(END) ?x- Next\: %x.:?pB%pB\%..%t

     And here is the default message produced by the = command:

	   ?f%f .?m(file %i of %m) .?ltlines %lt-%lb?L/%L. .
		   byte %bB?s/%s. ?e(END) :?pB%pB\%..%t

     The prompt expansion features are also used for another purpose: if an
     environment variable LESSEDIT is defined, it is used as the command to be
     executed when the v command is invoked.  The LESSEDIT string is expanded
     in the same way as the prompt strings.  The default value for LESSEDIT
     is:

	   %E ?lm+%lm. %f

     Note that this expands to the editor name, followed by a + and the line
     number, followed by the file name.	 If your editor does not accept the
     "+linenumber" syntax, or has other differences in invocation syntax, the
     LESSEDIT variable can be changed to modify this default.

SECURITY
     When the environment variable LESSSECURE is set to 1, less runs in a
     "secure" mode.  This means these features are disabled:

     !	     The shell command.

     |	     The pipe command.

     :e	     The examine command.

     v	     The editing command.

     s -o    Log files.

     -k	     Use of lesskey files.

     -t	     Use of tags files.

	     Metacharacters in filenames, such as "*".

	     Filename completion (TAB, ^L).

     Less can also be compiled to be permanently in "secure" mode.

ENVIRONMENT
     Environment variables may be specified either in the system environment
     as usual, or in a lesskey(1) file.	 If environment variables are defined
     in more than one place, variables defined in a local lesskey file take
     precedence over variables defined in the system environment, which take
     precedence over variables defined in the system-wide lesskey file.

     COLUMNS
	     Sets the number of columns on the screen.	Takes precedence over
	     the number of columns specified by the TERM variable.  (But if
	     you have a windowing system which supports TIOCGWINSZ or
	     WIOCGETD, the window system's idea of the screen size takes
	     precedence over the LINES and COLUMNS environment variables.)

     EDITOR  The name of the editor (used for the v command).

     HOME    Name of the user's home directory (used to find a lesskey file).

     LANG    Language for determining the character set.

     LC_CTYPE
	     Language for determining the character set.

     LESS    Options which are passed to less automatically.

     LESSANSIENDCHARS
	     Characters which are assumed to end an ANSI color escape sequence
	     (default "m").

     LESSBINFMT
	     Format for displaying non-printable, non-control characters.

     LESSCHARDEF
	     Defines a character set.

     LESSCHARSET
	     Selects a predefined character set.

     LESSCLOSE
	     Command line to invoke the (optional) input-postprocessor.

     LESSEDIT
	     Editor prototype string (used for the v command).	See discussion
	     under PROMPTS.

     LESSGLOBALTAGS
	     Name of the command used by the -t option to find global tags.
	     Normally should be set to "global" if your system has the global
	     command.  If not set, global tags are not used.

     LESSKEY
	     Name of the default lesskey(1) file.

     LESSKEY_SYSTEM
	     Name of the default system-wide lesskey(1) file.

     LESSMETACHARS
	     List of characters which are considered "metacharacters" by the
	     shell.

     LESSMETAESCAPE
	     Prefix which less will add before each metacharacter in a command
	     sent to the shell.	 If LESSMETAESCAPE is an empty string,
	     commands containing metacharacters will not be passed to the
	     shell.

     LESSOPEN
	     Command line to invoke the (optional) input-preprocessor.

     LESSSECURE
	     Runs less in "secure" mode.  See discussion under SECURITY.

     LESSSEPARATOR
	     String to be appended to a directory name in filename completion.

     LINES   Sets the number of lines on the screen.  Takes precedence over
	     the number of lines specified by the TERM variable.  (But if you
	     have a windowing system which supports TIOCGWINSZ or WIOCGETD,
	     the window system's idea of the screen size takes precedence over
	     the LINES and COLUMNS environment variables.)

     SHELL   The shell used to execute the ! command, as well as to expand
	     filenames.

     TERM    The type of terminal on which less is being run.

     VISUAL  The name of the editor (used for the v command).

STANDARDS
     The more utility is compliant with the IEEE Std 1003.1-2008 (``POSIX'')
     specification, though its presence is optional.

     The flags [-aBbCdEFfGghIJjkLMmNOoPQqRrSTUVWwXxyz~#] are extensions to
     that specification.

CAVEATS
     The = command and prompts (unless changed by -P) report the line numbers
     of the lines at the top and bottom of the screen, but the byte and
     percent of the line after the one at the bottom of the screen.

     If the :e command is used to name more than one file, and one of the
     named files has been viewed previously, the new files may be entered into
     the list in an unexpected order.

     On certain older terminals (the so-called "magic cookie" terminals),
     search highlighting will cause an erroneous display.  On such terminals,
     search highlighting is disabled by default to avoid possible problems.

     In certain cases, when search highlighting is enabled and a search
     pattern begins with a ^, more text than the matching string may be
     highlighted.  (This problem does not occur when less is compiled to use
     the POSIX regular expression package.)

     When viewing text containing ANSI color escape sequences using the -R
     option, searching will not find text containing an embedded escape
     sequence.	Also, search highlighting may change the color of some of the
     text which follows the highlighted text.

     On some systems, setlocale claims that ASCII characters 0 through 31 are
     control characters rather than binary characters.	This causes less to
     treat some binary files as ordinary, non-binary files.  To workaround
     this problem, set the environment variable LESSCHARSET to "ascii" (or
     whatever character set is appropriate).

     See http://www.greenwoodsoftware.com/less for the latest list of known
     bugs in this version of less.
