This program translates the main problem collection from Cho's
Encyclopedia of Life and Death to SGF format.
It was written by Ulrich Goertz (uligo@g0ertz.de), 2001, and is
based on a similar program written by Bill Shubert.
This program comes WITHOUT ANY WARRANTY! Only use it with
backups of the original files! This program is published under
the GNU General Public License (see the file gpl.txt).

Usage:
Copy this program (and the subdirectory Sgflib) into the directory with the 
files from the Encyclopedia (abc.dr and abc.dt are needed), and start it 
with 'python cho2sgf.py'.

Four SGF files will be written (abc-el.sgf, abc-im.sgf, abc-adv.sgf,
abc-oth.sgf; they contain the elementary, intermediate, advanced
and not classified problems of the database, respectively.)
They are ready to use with the uliGo program.
