Name
----
vercmp - version comparison utility
Synopsis
--------
'vercmp' [-h] [--help] <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 comparison operates as follows:
Alphanumeric:
1.0a < 1.0b < 1.0beta < 1.0p < 1.0pre < 1.0rc < 1.0 < 1.0.a < 1.0.1
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`.
Keep in mind that the 'pkgrel' is only compared if it is available on both
versions given to this tool. For example, comparing `1.5-1` and `1.5` will
yield 0; comparing `1.5-1` and `1.5-2` will yield < 0 as expected. This is
mainly for supporting versioned dependencies that do not include the 'pkgrel'.
