(I.e., support was dropped, not the source. Will be superseded by a SchemeQL port.)

is an implementation of the MySQL client/server protocol written entirely in Scheme.

The package is part of Eric Marsden's Downloads, also available from the local scsh contrib repository. An updated version is available from Emilio Lopes' Scheme page.
