Guilmon model by Reptilligator ( @Reptilligator on twitter! )
Ported by Damn Dirty DØG (@DamnDirtyD0G on twitter!)

Intended for SFM, but probably works in GMod with a bone manipulation tool.

Includes a rigging script (rig_guilmon), as well as a default animationset definition file so all the bones aren't listed under Unknown. Was built off of an extensive one I found but if you have a custom one of your own you may need to edit them together. Tried to keep it commented well.
