mod_tcl is a more complete link of Apache with Tcl. It makes available the full Apache C API so that it is possible to write Apache modules in Tcl. mod_tcl is only for Apache 2.0 at the moment, but will hopefully be the focus of future Apache Tcl efforts. If performance does not suffer, it should be possible to make available NeoWebScript or mod_dtcl modules for mod_tcl. Go to http://tcl.apache.org to read more about mod_tcl
