  1158. ## Usage. ##
  1159. ## ------ ##
  1160. # This file is a library for parsing options in your shell scripts along
  1161. # with assorted other useful supporting features that you can make use
  1162. # of too.
  1163. #
  1164. # For the simplest scripts you might need only:
  1165. #
  1166. # #!/bin/sh
  1167. # . relative/path/to/funclib.sh
  1168. # . relative/path/to/options-parser
  1169. # scriptversion=1.0
  1170. # func_options ${1+"$@"}
  1171. # eval set dummy "$func_options_result"; shift
  1172. # ...rest of your script...
  1173. #
  1174. # In order for the '--version' option to work, you will need to have a
  1175. # suitably formatted comment like the one at the top of this file
  1176. # starting with '# Written by ' and ending with '# warranty; '.
  1177. #
  1178. # For '-h' and '--help' to work, you will also need a one line
  1179. # description of your script's purpose in a comment directly above the
  1180. # '# Written by ' line, like the one at the top of this file.
  1181. #
  1182. # The default options also support '--debug', which will turn on shell
  1183. # execution tracing (see the comment above debug_cmd below for another
  1184. # use), and '--verbose' and the func_verbose function to allow your script
  1185. # to display verbose messages only when your user has specified
  1186. # '--verbose'.
  1187. #
  1188. # After sourcing this file, you can plug processing for additional
  1189. # options by amending the variables from the 'Configuration' section
  1190. # below, and following the instructions in the 'Option parsing'
  1191. # section further down.

  1199. # '--help' output messages. You can embed shell variables for delayed
  1200. # expansion at the time the message is displayed, but you will need to
  1201. # quote other shell meta-characters carefully to prevent them being
  1202. # expanded when the contents are evaled.
