TRF is a highly effective extension library designed for use with the script language Tcl. The library is credited to John Ousterhout, and it offers numerous features that enhance the overall quality of the script language at a C-level.

Overall, TRF is a powerful, reliable, and highly effective software extension that enhances the capabilities of the script language Tcl in numerous ways.
