[Openmcl-devel] %directory-string-list fails on real Mac filenames

[Gary King]

Hi,

You're probably aware of Olin Shivers work with the Scheme shell, but 
just in case you're not, 
http://citeseer.ist.psu.edu/shivers94scheme.html is a good 
introduction. I really like the idea of a nice Lisp shell built around 
OpenMCL.

Regards,
Gary
