chroottools.git is a fork of devtools.git, and is thus licensed GPLv2. devtools includes the program "makechrootpkg", which has been deleted in chroottools. However, some of the code from it has been copied into libretools.git, which is otherwise GPLv3+.

I think it might be a good idea to rework
makechrootpkg into "chroot-functions" or something to keep them
separated for licensing reasons, and so that I can pull devtools
changes to that code.
