Hey guys, stumbled on a necro thread that had instructions for a batch compiler for, the now defunct, Source SDK (2007).
The following should work for 2013. Hopefully it will help somebody.

(You do need to run the vbsp from Hammer to get the .bsp to continue compiling; I highly suggest getting the VBSP 2013 fix)

It's pretty much self-explanatory and works like the CS:GO compiler.
I'll check back if you need help. Also, open to suggestions.
