How do I make an .ent file so I can add some spawns w/o recompiling.
I'd like to add some spawns to frankishtowerctf (2 or 3 in the toweritself). I'd like to do this through an ent file so I don't have to recompile.

What is the step by step process to do so?

Also:
if I made the shader quickfixfrankishleaves.shader with a copy of
the shader that is supposed to be in the jcrveg shader file (but
is sometimes overridden by older versions of the file) will that work correctly? (IE there will
be 2 copies of the same shader script but diff named, but the
scripts will be the same)

sv_saveentfile then edit data/maps/yourmap.ent with your favorite text editor.

You can also just add more spawn points in Netradiant and compile with "update entities only" maybe called something else in your menu though. Use latest build from div0.
