 40      shebang if one exists.
 41  
 42          >>> from pygments.util import shebang_matches
 43          >>> shebang_matches('#!/usr/bin/env python', r'python(2\.\d)?')
 44          True
 45          >>> shebang_matches('#!/usr/bin/python2.4', r'python(2\.\d)?')
 46          True
 47          >>> shebang_matches('#!/usr/bin/python-ruby', r'python(2\.\d)?')
 48          False
 49          >>> shebang_matches('#!/usr/bin/python/ruby', r'python(2\.\d)?')
 50          False
 51          >>> shebang_matches('#!/usr/bin/startsomethingwith python',
 52          ...                 r'python(2\.\d)?')
 53          True
 54  
 55      It also checks for common windows executable file extensions::
 56  
 57          >>> shebang_matches('#!C:\\Python2.4\\Python.exe', r'python(2\.\d)?')
 58          True
 59  
 60      Parameters (``'-f'`` or ``'--foo'`` are ignored so ``'perl'`` does
 61      the same as ``'perl -e'``)
 62  
 63      Note that this method automatically searches the whole string (eg:
 64      the regular expression is wrapped in ``'^$'``)
