Hello, all. First off - I'm new here, so I don't know where I should have posted this, but here seemed alright.
Basically, this is a STool for Garry's Mod, which allows you to spawn any particle from most Valve games (Provided you have them installed). Since the particles from the emitter tool are very limited, this tool should come in handy. For example - You are doing a pose in Garry's Mod of someone taking a piss (Strange, I know, but remember what website we're on here! ;) ) you could spawn in a fitting particle. All credit goes to the rightful author of the addon.
