# Written by Michales Michaloudes korgie@gmail.com <2014>

# 20250207 bkw: modified by SlackBuilds.org, BUILD=2.
# These modifications were made with permission from the maintainer.
# - install apps in /usr/bin.
# - actually use SLKCFLAGS consistently.
# - de-uglify the build/install process. easier to read now.
