# Generates a module index file by searching through android source
# tree for make files.  The intellij-gen.sh script automatically calls
# this script the first time or if you delete the generated indexed
# file.  The only time you need to run this manually is if modules are
# added or deleted.
#
# To use, run the following command from either your repo root or
# development/tools/idegen:
#   index-gen.sh
#
# Only tested on linux.  Should work for macs but have not tried.
