'''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%|%.

The C parts of Tcllib can be build either via

======
configure ; make critcl
======

or

======
./sak.tcl critcl
======
