  When you use an a.out binary, it first looks in the same path under
/emul/aout (/emul/aout/usr/lib, etc.) for the library to load.  If you
move the old libraries there, you can use your a.out applications.  You
should move your a.out packages there too (and add it to your path).

  Unfortunately, the package system can't really deal with the upgrade
dependencies.  So you will probably want to reinstall all of your packages
as soon as possible.  At least, you should move /var/db/pkg to emul/aout
too (and maybe keep a.out pkg_* under /emul/aout too to easily delete them
as you recompile them elf).  If you don't, then you end up with elf
binaries that don't work because a library in a package they depend on is
a.out.  When it only depends on the binary, you should be able to copy the
entry from /emul/aout/var/db/pkg to /var/db/pkg (at least I think that
should work) until you want to recompile.
