Common Lisp symbols

["Stephen E. Robbins" <unido!OZ.AI.MIT.EDU!STEVER@seismo.CSS.GOV>]

The company I work for is just starting a large project
in Common Lisp.  For portability, we'd like to create our
own special package into which we IMPORT the implementation's
Common Lisp and then EXPORT *exactly* the set of CLtL symbols
that make up common lisp.  Our packages will then USE our
private CL package.

Does anyone out there have a list of the symbols in CLtL?
Or is this going to require going through the manual page 
by page and figuring out what needs to be [im]ported?
