SGRAB DOCUMENTATION
-------------------

SGRAB [-s | -c] [-p] filename
	-s	force seperate files
	-c	force a composite .DAT file (default)
	-p	wait for a keypress after each grab command


Filename should be the root (no extension) of the picture (.LBM) to be
grabbed.  The script file (.SCR) is read in and parsed, causing lumps to be
grabbed off the screen and saved into an output data (.DAT) file.

If the -s option is used, or the first command in the script file is
$SEPERATE, the lumps are each saved to a seperate file, rather than being
combined into a composite file.


The script file format is as follows:

[$SEPERATE]
lumpname	grabcommand	[parameters]
; Comments can be uses at the beginning of a line, or after a command's parms
; whitespace can be introduced anywhere, but a command cannot cross lines



If the lumps are being saved individually, lumpname can be any valid pathname,
but for composite files it must be a filename[.ext] size.
