# v4 of the gcc compiler uncovered an error in the code that should be corrected in
# the 5.08 version of gnuchess.
#
# The error:
# input.c:95: error: static declaration of ‘input_thread’ follows non-static declaration
#
# The patch removes 'static' from the declaration in input.c. See msg at
# http://www.mail-archive.com/bug-gnu-chess@gnu.org/msg00218.html

The README file contains a manual for use:
#{doc}/README
This formula also downloads the additional opening book. The opening
book is a gzipped PGN file that can be added using gnuchess commands.
The book_*.pgn.gz file is located in the same directory as the README.
See the README for using the `book add' command.
