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.
