trf: trf (transformer extension library for Tcl) trf: trf: Trf extends the TCL language at the C-level with so-called trf: ``transformer'' procedures. With the help of some patches to the core trf: the package is able to intercept all read/write operations on trf: designated channels, thus giving it the ability to transform the trf: buffer contents as desired. This allows things like transparent trf: encryption, compression, charset recoding, etc. trf: trf: https://core.tcl.tk/akupries/soft/trf/index.html trf:
