#!/usr/bin/awk -f

# This awk script creates function impls that can be used in the C callbacks
# with some little adjustments; eg:
# rts/ExternalAI/SSkirmishAICallbackImpl.cpp
# rts/ExternalAI/SAIInterfaceCallbackImpl.cpp
#
# Accepts input like this:
# [code]
# bool allowTeamColors;
#
# // construction related fields
# /// Should constructions without builders decay?
# bool constructionDecay;
# [/code]
#
# use like this:
# awk -f yourScript.awk -f common.awk -f commonDoc.awk [additional-params]
# this should work with all flavours of AWK (eg. gawk, mawk, nawk, ...)
#
BEGIN {
# initialize things
# define the field splitter(-regex)
#FS="[ \t]+"
# 0 -> print impl
# 1 -> print impl header
# 2 -> print interface header
