This includes info on version comparison that is very similar to the stuff in the pacman manpage, but also a few vercmp examples, the return values, and other fun stuff. Also update the version comparison stuff in the pacman manpage. Signed-off-by: Dan McGee <dan@archlinux.org>

vercmp - version comparsion utility
|
|
|
|
|
|
Synopsis
|
|
--------
|
|
'vercmp' <version1> <version2>
|
|
|
|
|
|
Description
|
|
-----------
|
|
'vercmp' is used to determine the relationship between two given version
|
|
numbers. It outputs values as follows:
|
|
|
|
* < 0 : if ver1 < ver2
|
|
* = 0 : if ver1 == ver2
|
|
* > 0 : if ver1 > ver2
|
|
|
|
Version comparsion operates as follows:
|
|
|
|
Alphanumeric:
|
|
1.0a < 1.0alpha < 1.0b < 1.0beta < 1.0p < 1.0pre < 1.0rc < 1.0
|
|
Numeric:
|
|
1 < 1.0 < 1.1 < 1.1.1 < 1.2 < 2.0 < 3.0.0
|
|
|
|
Additionally, version strings can have an 'epoch' value defined that will
|
|
overrule any version comparison (unless the epoch values are equal). This is
|
|
specified in an `epoch:version-rel` format. For example, `2:1.0-1` is always
|
|
greater than `1:3.6-1`.
