Picol is a fun-size Tcl interpreter: the version found in this repository is around 3 KSLOC. Picol was originally written by Salvatore Sanfilippo and then extended by Richard Suchenwirth in 2007.

This fork splits it into a library (picol.h) for embedding the interpreter in other applications and a REPL program (interp.c) and includes a number of fixes for correctness and Tcl 8.x compatibility. Examples of programs that embed Picol can be found in the directory examples/.

Note that Picol is not intended for production use.
