+Lucas Chess is a flexible and powerful chess software created by Lucas Monge.
+It includes 61 pre-installed engines with a wide range of ELO levels,
+including the neural network engines of the Maia project that emulate human
+play based on a certain ELO. It also includes a wide range of training modules
+to improve your chess skills. It can perform game analysis, generate custom
+trainings based on your mistakes, read PGN files, and study openings.
+
+This SlackBuild repackages the binary distribution provided by upstream. It
+requires about 700 MB of space when installed.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
