| looseversion.py |
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)
