+PyWayland provides a wrapper to the libwayland library using the CFFI
+library to provide access to the Wayland library calls and written in

+
+python3-pywayland 0.4.14 is the last possible version for Slackware
+15.0. Newer versions of python3-pywayland require a newer
+python-setuptools.

+# 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.
