# Slackware build script for ydotool

# Written by B. Watson (yalhcru@gmail.com)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Note: this is not the latest version of ydotool, though it's newer
# than the version that Debian packages. It uses the stable(ish)
# libevdevplus and libuinputplus versions that Debian also packages.

# Later ytodool, libevdevplus, and libuinputplus versions are
# rapidly-moving targets for now. Plus, latest ydotool uses "CPM"
# (Cmake Package Manager) to auto-download its dependencies, and I
# haven't had time to figure out how to defeat that so the script can
# run without doing network access...
