NAME
       gij - GNU interpreter for Java bytecode

SYNOPSIS
       gij [OPTION] ... JARFILE [ARGS...]

       gij [-jar] [OPTION] ... CLASS [ARGS...]
	 [-cp path] [-classpath path]
	 [-Dname[=value]...]
	 [-ms=number] [-mx=number]
	 [-Xargument] [-verbose] [-verbose:class]
	 [--showversion] [--version] [--help][-?]

DESCRIPTION
       "gij" is a Java bytecode interpreter included with "libgcj".  "gij" is
       not available on every platform; porting it requires a small amount of
       assembly programming which has not been done for all the targets
       supported by gcj.

       The primary argument to "gij" is the name of a class or, with "-jar", a
       jar file.  Options before this argument are interpreted by "gij";
       remaining options are passed to the interpreted program.

       If a class name is specified and this class does not have a "main"
       method with the appropriate signature (a "static void" method with a
       "String[]" as its sole argument), then "gij" will print an error and
       exit.

       If a jar file is specified then "gij" will use information in it to
       determine which class' "main" method will be invoked.

       "gij" will invoke the "main" method with all the remaining command-line
       options.

       Note that "gij" is not limited to interpreting code.  Because "libgcj"
       includes a class loader which can dynamically load shared objects, it
       is possible to give "gij" the name of a class which has been compiled
       and put into a shared library on the class path.

OPTIONS
       -cp path
       -classpath path
	   Set the initial class path.	The class path is used for finding
	   class and resource files.  If specified, this option overrides the
	   "CLASSPATH" environment variable.  Note that this option is ignored
	   if "-jar" is used.

       -Dname[=value]
	   This defines a system property named name with value value.	If
	   value is not specified then it defaults to the empty string.	 These
	   system properties are initialized at the program's startup and can
	   be retrieved at runtime using the "java.lang.System.getProperty"
	   method.

       -ms=number
	   Equivalent to "-Xms".

       -mx=number
	   Equivalent to "-Xmx".

       -noverify
	   Do not verify compliance of bytecode with the VM specification. In
	   addition, this option disables type verification which is otherwise
	   performed on BC-ABI compiled code.

       -X
       -Xargument
	   Supplying "-X" by itself will cause "gij" to list all the supported
	   "-X" options.  Currently these options are supported:

	   -Xmssize
	       Set the initial heap size.

	   -Xmxsize
	       Set the maximum heap size.

	   -Xsssize
	       Set the thread stack size.

	   Unrecognized "-X" options are ignored, for compatibility with other
	   runtimes.

       -jar
	   This indicates that the name passed to "gij" should be interpreted
	   as the name of a jar file, not a class.

       --help
       -?  Print help, then exit.

       --showversion
	   Print version number and continue.

       --fullversion
	   Print detailed version information, then exit.

       --version
	   Print version number, then exit.

       -verbose
       -verbose:class
	   Each time a class is initialized, print a short message on standard
	   error.

       "gij" also recognizes and ignores the following options, for
       compatibility with existing application launch scripts: "-client",
       "-server", "-hotspot", "-jrockit", "-agentlib", "-agentpath", "-debug",
       "-d32", "-d64", "-javaagent", "-noclassgc", "-verify", and
       "-verifyremote".
