\ Text strings translation tool
\ Program written in Forth; developed with Forth 5mx and Gforth.

\ History
\ ------------------------------------------

\ 2005-11-01
\   Start. Algorithm to translate chars into strings.
\ 2005-11-10
\   Rewrite. New improved algorithm to translate strings into strings.
\ 2005-11-11
\   Bugs fixed. It seems it works.
\ 2007-05-08
  \ 'translate-more?' factored out from 'tra'.
\   Bug fixed in 'tra' :
\   The translation halted when the last word in the text had to be translated but
\   it was shorter than the first word in the translation table.
\   The best order for the elements in the translation table is not solved yet.
\   Provisional solution: remove that condition.
\ 2013-12-10
\   Source code style and stack notation updated.
\   '-left' removed, '/string' does exactly the same.
\   '.tra-table-element' factored from '.tra-table'.
\   Some comments fixed.
