I do it manually, but I have a script that checks for programs in the
base system and packages that use any library moved to the lib/compat
directory - see below.
The base system checks should never give any output (unless there are
old and obsolete binaries).
I use the package list to identify packages that must be rebuilt to
make the compat libraries obsolete. Since there may be shared library
version conflicts, if some
