Where are the weapon_* entities defined in JK2's source code?

[T.Zealot]

Alright, I downloaded the JK2 source code that eezstreet fixed up and I've been trying to add a custom weapon. I have it set up in ext_data, gave the weapon its own WP_ entry, etc. But I have no idea how to add the weapon_ entity itself, and I am completely stumped since when I search for a weapon in the solution explorer I.E. weapon_blaster nothing shows up. If somebody can help me out then I'd really appreciate it, thank you in advance.

I'm pretty sure weapon_* are defined in weapons.dat, which point to their code version which is WP_*
