SwarmTools adds natives and stocks that are useful for Alien Swarm plugin developers.
The attached swarmtools.inc may be required to compile some plugins, and the SwarmTools plugin itself may be required on the server for some Alien Swarm plugins to run.
In Alien Swarm, the player/client entity is separate from the marine entity. There is then a third entity type, a marine resource, that links these two together.
This plugin provides a few natives to make converting between client and marine seemless. There are also many useful stocks provided to simplify plugin development.

If you are not using any of the natives or any of the stocks that require the natives and do not wish to require the plugin, you can add it as such:
If you post a plugin requiring it, put the SwarmTools plugin id into the dependency field so that users can easily find it.
Thank you to comp_noob for doing all of the testing.
