class LooseVersion(Version) |

Version numbering for anarchists and software realists.
Implements the standard interface for version number classes as
described above. A version number consists of a series of numbers,
separated by either periods or strings of letters. When comparing
version numbers, the numeric components will be compared
numerically, and the alphabetic components lexically. The following
are all valid version numbers, in no particular order:
1.5.1
1.5.2b2
161
3.10a
8.02
3.4j
1996.07.12
3.2.pl0
3.1.1.6
2g6
11g
0.960923
2.2beta29
1.13++
5.5.kw
2.0b1pl0
In fact, there is no such thing as an invalid version number under
this scheme; the rules for comparison are simple and predictable,
but may not always give the results you want (for some definition
of "want"). |

class StrictVersion(Version) |

Version numbering for anal retentives and software idealists.
Implements the standard interface for version number classes as
described above. A version number consists of two or three
dot-separated numeric components, with an optional "pre-release" tag
on the end. The pre-release tag consists of the letter 'a' or 'b'
followed by a number. If the numeric components of two version
numbers are equal, then one with a pre-release tag will always
be deemed earlier (lesser) than one without.
The following are valid version numbers (shown in the order that
would be obtained by sorting according to the supplied cmp function):
0.4 0.4.0 (these two are equivalent)
0.4.1
0.5a1
0.5b3
0.5
0.9.6
1.0
1.0.4a3
1.0.4b1
1.0.4
The following are examples of invalid version numbers:
1
2.7.2.2
1.3.a4
1.3pl1
1.3c4
The rationale for this version numbering system will be explained
in the distutils documentation. |

class Version |

Abstract base class for version numbering classes. Just provides
constructor (__init__) and reproducer (__repr__), because those
seem to be the same for all version numbering classes. |
