The supplied q2e1m7.ent enables the map to be played using CTF entities. It can be used in a number of ways:-
1) use qbsp3.exe to apply it as follows (This is generally for use with Zoids Quake2 CTF)

qbsp3 -onlyents c:\quake2\baseq2\maps\q2e1m7.ent

If the bsp is in the same directory as the ent file then the entities will be changed accordingly

2) For use with L-Fire CTF put the .ent file in the ent directory in the L-Fire CTF directory

Im sorry I cannot be more specific but I do not play CTF and have only recently been informed of this ability
Read the documentation supplied with the CTF mod on how to use the .ent file accordingly.
