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.
