+    # 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
+    #   }
