lmk-run
-------
This script is part of <https://github.com/poikilos/EnlivenMinetest>.

Does all of the following
- Gets and unzips linux-minetest-kit.zip if possible if there is no
  linux-minetest-kit in the current working directory.
- Compile libraries if there is no linux-minetest-kit/toolstree.
- Compile minetest if there is no exe matching the specified options.

Suggested setup for a user in the sudo group:
'''
chgrp sudo /opt
# continue to Further setup
'''

Suggested setup for minebest user:
'''
chgrp minebest /opt
# continue to Further setup
'''

Further setup:
'''
chmod g+w /opt
cd /opt

'''

Examples:
lmk-run classic client ~/minetest/worlds/center
# ^ creates classic client and opens the world ~/minetest/worlds/center
#   - requires that the game is in linux-minetest-kit/minetest/games
#     that has the gameid matching the one in the world (same goes for
#     any of the automatically checked world paths).

lmk-run classic server
# ^ creates minetestserver

lmk-run finetest server
# ^ creates finetestserver

lmk-run trolltest server
# ^ creates trolltestserver

lmk-run classic client
# ^ creates minetest

lmk-run finetest client
# ^ creates finetest

lmk-run trolltest client
# ^ creates trolltest
