  28 # Script used as a base to generate components of enums,
  29 # as cited in prototypes.sh
  30 #
  31 # Output is a tab-separated two columns of the form:
  32 #
  33 # item_name     value
  34 #
  35 # Note: Although this _should_ be portable across UNIXes,
  36 # it has not been tested (successfully, of course) on anything but:
  37 #
  38 #       - GNU Bourne-Again Shell (GNU bash) 3.00.0 and
  39 #         NetBSD Bourne Shell (ash) 1.6.0
  40 #
  41 # Please also note it will not likely work without GNU sed
  42 # (tested on GNU Streaming EDitor - GNU sed - 4.0.9 ), since
  43 # it makes use of many GNU extensions (characters classes, \U, etc).
  44 #
  45 # Finally, you will need bc (any version: very basic use) to run this
  46 # since we do not use shell arithmetic.
