Provides classes to represent module version numbers (one class for each style of version numbering). There are currently two such classes implemented: StrictVersion and LooseVersion. Every version number class implements the following interface: * the 'parse' method takes a string and parses it to some internal representation; if the string is an invalid version number, 'parse' raises a ValueError exception * the class constructor takes an optional string argument which, if supplied, is passed to 'parse' * __str__ reconstructs the string that was passed to 'parse' (or an equivalent string -- ie. one that will generate an equivalent version number instance) * __repr__ generates Python code to recreate the version number instance * _cmp compares the current instance with either another instance of the same class or a string (which will be parsed to an instance of the same class, thus must follow the same rules)
| Class | |
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... |

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... |
| Class | |
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; and route rich comparisons to _cmp. |
