#
# Listaller uses .IPK files for cross-distro installations. It's well
# integrated with Freedesktop schemes and distro application managers.
# 
# This module just chains to the generation tool currently, and builds
# static / unrelocatable packages. (Proper support would require using
# Listallers relaytool + ligcc when building the app binaries.)
