-# =GZip Simple
-#
-# A simplified interface to the gzip library +zlib+ (from the Ruby Standard Library.)
-#
-# Author: murphy (mail to murphy rubychan de)
-#
-# Version: 0.2 (2005.may.28)
-#
-# ==Documentation
-#
-# See +GZip+ module and the +String+ extensions.
-#
-module GZip

-  require 'zlib'
-
-  # The default zipping level. 7 zips good and fast.
-  DEFAULT_GZIP_LEVEL = 7

-  # Example:
-  #   require 'gzip_simple'
-  #   print GZip.gunzip(File.read('adresses.gz'))
-  def GZip.gunzip s
-    Zlib::Inflate.inflate s

-  # the string is compressed:
-  # - 0: no compression, only convert to gzip format
-  # - 1: compress fast

-#   # zip it
-#   x_gz = x.gzip
-#

-#   puts 'Zipped %d bytes to %d bytes.' % [x.size, x_gz.size]

-# A WordList is a Hash with some additional features.
-# It is intended to be used for keyword recognition.
-#
-# WordList is highly optimized to be used in Scanners,
-# typically to decide whether a given ident is a special token.
-#
-# For case insensitive words use CaseIgnoringWordList.
-#
-# Example:
-#
-#  # define word arrays
-#  RESERVED_WORDS = %w[
-#    asm break case continue default do else
-#    ...
-#  ]
-#  
-#  PREDEFINED_TYPES = %w[
-#    int long short char void
-#    ...
-#  ]
-#  
-#  PREDEFINED_CONSTANTS = %w[
-#    EOF NULL ...
-#  ]
-#  
-#  # make a WordList
-#  IDENT_KIND = WordList.new(:ident).
-#    add(RESERVED_WORDS, :reserved).
-#    add(PREDEFINED_TYPES, :pre_type).
-#    add(PREDEFINED_CONSTANTS, :pre_constant)

-#  def scan_tokens tokens, options
-#    ...
