Description:

    # We do not use urllib's builtin pathname2url() function since:
    #  - it has been commented with 'not recommended for general use'
    #  - it does not seem to work the same on Windows and non-Windows platforms
    #    (result starts with /// on Windows but does not on others)
    #  - urllib implementation prior to Python 2.5 used to quote ':' characters
    #    as '|' which would confuse pip on Windows.
