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