tclexecomp is a TCL exectutable wrapper, which creates a single executable file from a tcl script.
Currently it can create binaries for Linux (64 Bit), Windows (32Bit /64 Bit) and MACOS (64 Bit).
It is based on freewrap (http://freewrap.sourceforge.net/ ), but more up-to-date and with many more tcl-modules integrated.
