	
	FSUBST.EXE is a small utility that will substitute flat names
in a Doom 1 or 2 wad. The file FSUBST.DAT must contain lines of the
form: "TLITE6_5 = RROCK05". White space may be used freely. The line 
shown will cause the RROCK05 flat to be substituted everywhere the 
TLITE6_5 flat occurs. There are no comment facilities currently.

	FSUBST syntax is simple:

	FSUBST wadname.wad [c] [f]

	Use the optional c or f parameter to restrict substitution to
ceilings or floors resp.

       WARNING:	This program is in alpha stage. Back up all work before
using FSUBST or suffer the consequences. 

	A companion utility WSUBST.EXE that does the same thing for
walls and allows restriction to 1st or 2nd sidedef textures, or upper, normal, 
or lower textures, or any combination, might be available in a few days...
