# Map the path according to the given specification.  The specification
    # controls the details of the mapping.  The following special patterns are
    # recognized:
    #
    # <tt>%p</tt> :: The complete path.
    # <tt>%f</tt> :: The base file name of the path, with its file extension,
    #                but without any directories.
    # <tt>%n</tt> :: The file name of the path without its file extension.
    # <tt>%d</tt> :: The directory list of the path.
    # <tt>%x</tt> :: The file extension of the path.  An empty string if there
    #                is no extension.
    # <tt>%X</tt> :: Everything *but* the file extension.
    # <tt>%s</tt> :: The alternate file separator if defined, otherwise use #
    #                the standard file separator.
    # <tt>%%</tt> :: A percent sign.
    #
    # The <tt>%d</tt> specifier can also have a numeric prefix (e.g. '%2d').
    # If the number is positive, only return (up to) +n+ directories in the
    # path, starting from the left hand side.  If +n+ is negative, return (up
    # to) +n+ directories from the right hand side of the path.
    #
    # Examples:
    #
    #   'a/b/c/d/file.txt'.pathmap("%2d")   => 'a/b'
    #   'a/b/c/d/file.txt'.pathmap("%-2d")  => 'c/d'
    #
    # Also the <tt>%d</tt>, <tt>%p</tt>, <tt>%f</tt>, <tt>%n</tt>,
    # <tt>%x</tt>, and <tt>%X</tt> operators can take a pattern/replacement
    # argument to perform simple string substitutions on a particular part of
    # the path.  The pattern and replacement are separated by a comma and are
    # enclosed by curly braces.  The replacement spec comes after the %
    # character but before the operator letter.  (e.g. "%{old,new}d").
    # Multiple replacement specs should be separated by semi-colons (e.g.
    # "%{old,new;src,bin}d").
    #
    # Regular expressions may be used for the pattern, and back refs may be
    # used in the replacement text.  Curly braces, commas and semi-colons are
    # excluded from both the pattern and replacement text (let's keep parsing
    # reasonable).
    #
    # For example:
    #
    #    "src/org/onestepback/proj/A.java".pathmap("%{^src,class}X.class")
    #
    # returns:
    #
    #    "class/org/onestepback/proj/A.class"
    #
    # If the replacement text is '*', then a block may be provided to perform
    # some arbitrary calculation for the replacement.
    #
    # For example:
    #
    #   "/path/to/file.TXT".pathmap("%X%{.*,*}x") { |ext|
    #      ext.downcase
    #   }
    #
    # Returns:
    #
    #  "/path/to/file.txt"
    #
    # This String extension comes from Rake
