DESCRIPTIONcompver is an ASCII file used to specify previous versions of the asso‐
ciated package which are upward compatible. It is created by a package
developer.
Each line of the file specifies a previous version of the associated
package with which the current version is backward compatible.
Since some packages may require installation of a specific version of
another software package, compatibility information is extremely cru‐
cial. Consider, for example, a package called A which requires version
1.0 of application B as a prerequisite for installation. If the cus‐
tomer installing A has a newer version of B (version 1.3), the compver
file for B must indicate that 1.3 is compatible with version 1.0 in
order for the customer to install package A.
EXAMPLES
Example 1 Using a compver File
A example of a compver file is shown below:
Version 1.3
Version 1.0
SEE ALSOpkginfo(4)NOTES
The comparison of the version string disregards white space and tabs.
It is performed on a word-by-word basis. Thus, Version 1.3 and Version
1.3 would be considered the same.
The entries in the compver file must match the values assigned to the
VERSION parameter in the pkginfo(4) files.
