# compare and rebuild packages on different architecture
#
# TODO
#
# - use a cache (rpmctl cache for example) to find maintainer
# - add icecream compilation support
# - add a --group option to compile a set of packages (in progress)
# - add a function to update a packages when it obviously need to be recompile
# - Maybe call the function from the initial todo list (thus making the argument ordering important)
# - Change the packager tag in the chroot to have the one who submit the package
