tclexecomp is a Tcl executable wrapper, which creates a single executable file from a Tcl script.
Currently it can create binaries for Linux (64-bit), Windows (32-bit/64-bit) and macOS (64-bit).
It is based on Freewrap, but more up-to-date and with many more Tcl modules integrated.

The latest version (released August 31, 2017) is V1.0.6 and uses Tcl 8.6.7.
