# Yet Another Resource Builder
#
# Usage:
#
##$ mkdir loc
##$ echo 'root { hello { "Hello" } }' > loc/root.txt
##$ echo 'es { hello { "Hola" } }' > loc/es.txt
##$ rm -rf ./out
##$ bldicures.py --name myapp --from ./loc -d ./out
##$ ls out/myapp.dat
#
# use 'bldicures.py --help' for help.
#
# BUGS/TODO
# * dependency calculation
# * pathnames/PATH for genrb/pkgdata
# * cleanup of files, ./out, etc
# * document res_index
# * probably pathname munging
# * deuglify python
