-    # <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|

-  # A FileList is essentially an array with a few helper methods defined to
-  # make file manipulation a bit easier.
-  #
-  # FileLists are lazy.  When given a list of glob patterns for possible files
-  # to be included in the file list, instead of searching the file structures
-  # to find the files, a FileList holds the pattern for latter use.

-    # delegates to the @items array and returns the result directly.  Well,
-    # almost directly.  It checks if the returned value is the @items object
-    # itself, and if so will return the FileList object instead.
-    #
-    # The second kind of delegation call is used in methods that normally
-    # return a new Array object.  We want to capture the return value of these
-    # methods and wrap them in a new FileList object.  We enumerate these
