IF you want to write a letter you do not
need a big word processor.
With tk_brief exists a small helper that produces professional letter with TeX with few expenditure.
The final letter is derived with TeX to get the best result (Screenshot).
You need the additional TeX package g-brief. The S.u.S.E. distribution
has already included g-brief.
Additional the program uses TCL/TK 8.0 (also included in S.u.S.E.).
tk_brief is a small and well done program in a nearly final state
that helps saving work.
