It's not exactly what you want but...
ftp cs.rochester.edu:/pub/knowledge-tools/CL-LIB* [192.5.53.209]
Parts of this package is also available via CMU (see the lisp FAQ).
after uncompressing/untarring you'll find a file called resources.lisp which implementes a resources package for allegro
similar to the one available on the symbolics. Think of it as user-level memory allocation.
There is also a re to dfa package. Not exactly what you want, but you can probably adapt it.
Good luck,
Brad Miller
