# We have three startup scripts:
# - tuhi: starts server and GUI
# - tuhi-gui: starts the GUI only
# - tuhi-server: starts the server only
#
# tuhi-server can run as-is, we don't need meson for it. But for the other
# two we build a {name}.devel version that uses the in-tree files.
# For that we need to replace a few paths, in the installed versions we just
# use the normal dirs.
