>>> v = VersionPredicate('pyepat.abc (>1.0, <3333.3a1, !=1555.1b3)')
The `name` attribute provides the full dotted name that is given::
>>> v.name
'pyepat.abc'
The str() of a `VersionPredicate` provides a normalized
human-readable version of the expression::
>>> print(v)
pyepat.abc (> 1.0, < 3333.3a1, != 1555.1b3)
The `satisfied_by()` method can be used to determine with a given
version number is included in the set described by the version
restrictions::
>>> v.satisfied_by('1.1')
True
>>> v.satisfied_by('1.4')
True
>>> v.satisfied_by('1.0')
False
>>> v.satisfied_by('4444.4')
False
>>> v.satisfied_by('1555.1b3')
False
`VersionPredicate` is flexible in accepting extra whitespace::
>>> v = VersionPredicate(' pat( == 0.1 ) ')
>>> v.name
'pat'
>>> v.satisfied_by('0.1')
True
>>> v.satisfied_by('0.2')
False
If any version numbers passed in do not conform to the
restrictions of `StrictVersion`, a `ValueError` is raised::
>>> v = VersionPredicate('p1.p2.p3.p4(>=1.0, <=1.3a1, !=1.2zb3)')
Traceback (most recent call last):
...
ValueError: invalid version number '1.2zb3'
It the module or package name given does not conform to what's
allowed as a legal module or package name, `ValueError` is
raised::
>>> v = VersionPredicate('foo-bar')
Traceback (most recent call last):
...
ValueError: expected parenthesized list: '-bar'
>>> v = VersionPredicate('foo bar (12.21)')
Traceback (most recent call last):
...
ValueError: expected parenthesized list: 'bar (12.21)'

The version number, if given, will be returned as a `StrictVersion`
instance, otherwise it will be `None`.
