# This script creates a debugging and testing environment when working on the policy
# Basically a fancy wrapper for "tar --exclude-vcs -cJf selinux-policy-20230321.tar.xz --transform 's,^,selinux-policy-20230321/,' -C selinux-policy ."
# 
# 1. Get the git repository with 'osc service manualrun' or './update.sh'
# 2. Do your changes in the selinux-policy repository, test around
# 	1. When you want to build locally to debug, call this script. It will create a .tar.xz with your current selinux-policy working directory.
# 	2. Build locally: e.g. with osc build
#	3. Test your rpms that contain your changes and repeat 
# 3. When finished, commit your changes in the selinux-policy repository and push to git
# 4. Run './update.sh' and checkin the changes to OBS
