Compare package versions in all their varied glory.
Description
This module provides the compare() function which compares two
version strings and returns a negative value, zero, or a positive
value depending on whether the first string represents a version
number lower than, equal to, or higher than the second one, and
the key_compare() function which may be used as a key for e.g.
sorted().
This module does not strive for completeness in the formats of version strings that it supports. Some version strings sorted by its rules are:
- 0.1.0
- 0.2.alpha
- 0.2
- 0.2.1
- 0.2a
- 0.2a.1
- 0.2a3
- 0.2a4
- 0.2p3
- 1.0~bpo3
- 1.0.beta
- 1.0.beta.2
- 1.0.beta2
- 1.0.beta3
- 1.0
- 1.0.4
- 1:0.3
