From the package man-page: MySQLTcl is a collection of Tcl commands and a Tcl global array that provide access to one or more mysql database servers. MySQLTcl is nothing more than a patched version of a patched version of Hakan Soderstrom's patch of Tom Poindexter's Sybtcl. Most of the documentention has been left as it was when I started to work with this interface (a patch of msqltcl-1.50). However, I have tried to replace appropriate occurrences of msql by MySQL.
