From the software's self-description:

Trf is a TCL extension library. It extends the language at the C-level with so-called ``transformer''-procedures. The package is able to intercept all read/write operations on designated channels, thus giving it the ability to transform the buffer contents as desired. This allows things like transparent encryption, compression, charset recoding, etc. Build upon this framework (and as proof of concept) a collection of tcl-level commands was implemented, most of them related to cryptography.

+	for the reasons unknown to me. The failures may, in
+	fact, be justified, but the software author is yet

+This  is  a  loadable  extension  to Tcl  providing  commands  for  data
+conversion, message  digests, zlib based  compression, error-correction,
+channel-based manipulation of  binary data. Trf extends  the language at
+the C-level with so-called  ``transformer''-procedures. With the help of
+some  patches (*)  to the  core  the package  is able  to intercept  all
+read/write operations on designated channels, thus giving it the ability
+to transform  the buffer  contents as desired.  This allows  things like
+transparent encryption,  compression, charset recoding, etc.  Build upon
+this  framework (and  as proof  of  concept) a  collection of  tcl-level
+commands was implemented.
