rlwrap [http://utopia.knoware.nl/~hlub/rlwrap/] is a GNU [readline] wrapper. it adds readline editing and command history to any command line app.

To use it with tclsh, start tclsh with:
======
rlwrap tclsh
======

Useful options are -c (file name completion) and -f (add words from a file to the completion list).

To use rlwrap with tclsh with file name completion type:
======
rlwrap -c tclsh
======

It would be nice to have a file of all words used in Tcl: commands and subcommands to set rlwrap up using the -f option.

[info commands] and [info procs] could help with that. Maybe there are some *.syn files out there to provide such a database.

[tclreadline] is another way of using readline with Tcl, but requires compiling Tcl and many people report difficulties in getting it to compile.
