ssqlfs is an application which generates a SQL database which corresponds to a defined file/directory structure. Along with support for one-to-many tables, ssqlfs includes support for representing many-to-many tables.

ssqlfs is written in common lisp. Ideally, the filesystem would be interconvertible with an SQL database but at this point the functions for generating a file/directory structure from the SQL database are in a relatively 'alpha' state and remain to be thoroughly tested.

ssqlfs has been developed using SBCL. It depends on several lisp packages including clsql, cl-ppcre, and cl-fad. The program is released under the LLGPL.
