Instructions on how to install:

When adding the several plugins into your plugins.ini, they must be in this order:

jumpstats_main.amxx
jumpstats_long.amxx
jumpstats_count.amxx
jumpstats_bhop.amxx
jumpstats_ladder.amxx
jumpstats_weird.amxx

If you do not place them in this order, bugs may occur.

If you are using plugins that can cheat jumps such as /checkpoint, +hook, etc.
Then you need to place those plugins BELOW these jumpstats plugins in the plugins.ini

Do not forget to add the sounds to your server in the directory provided.
Not adding them may cause your server to crash, or other problems.

All cvars and their descriptions are placed in the configs/jumpstats.cfg file.
There are too-many-to-count cvars (most of them are divided among different jump techniques).
