'''Tcllibc''' is a term used to refer to the parts of [Tcllib] written in [C]. Some packages in Tcllib provide two implementations, one written in [pure Tcl] for compatibility and low installation overhead and one written in C for speed. [ActiveTcl] has a separate [Tcl Extension Archive] package called http://docs.activestate.com/activetcl/8.6/tcllibc/tcllibc.html%|%Tcllibc%|%. <>Glossary | Package | Tcllib
