An easy way to package a plugin?

[nilead]

 Ive got an old NMM installation of SSE lying around, wich contains a large number of custom assets accumulated over a long time.

Manually packaging such is a chore to say the least. Is there, perhaps, a more convenient tool or funciton? Something akin to packaging projects in, say,  blender, where neccecery file structure and used assets are packed automaticly for selected project?
