# Use fpm to package up files into an RPM.
# Usage:
# mk_rpm_fpmdir PACKAGENAME MANIFEST1 MANIFEST2 ...
# Example:
# Make a package foopkg manifest.txt
# Where "manifest.txt" contains:
# exec /usr/bin/stack_makefqdn misc/stack_makefqdn.py
# exec /usr/bin/bar bar/bar.sh
# read /usr/man/man1/bar.1 bar/bar.1.man
# 0444 /etc/foo.conf bar/foo.conf
