Hi All you Eager MPEG Makers, here is how to port the PVRG MPEG
encoder/decoder to DOS/PC (386).

Tools required:
	Well the ones that I used.

		GNU C version 2.2.2
		An uncompress util for UNIX .Z files
		An untar util for UNIX tar files
		Text Editor (sorry some code needs tweaked)
		Note: Diff from the GNU File utilities, could be used instead
Source required:
		/pub/mpeg/MPEGv1.2.alpha.tar.Z
			from havefun.stanford.edu

		/pub/mpeg/MPEGDOCv1.1.tar.Z
			from havefun.stanford.edu
			documentation still to be updated.

Step 1
	Decompress the .Z files

Step 2 
	Untar the resulting tar files.
	Note that 2 of the file names won't fit in the DOS 8 and 3 name format:
		transform.c truncates to transfor.c
		prototype.h truncates to prototyp.h

Step 3
	Apply patch1 to mem.c
	Apply patch2 to stream.c
	Apply patch3 to mpeg.c

	All that is happening here is that the fopen mode is be changed to
	ensure that files are opened in binary mode, as DOS compilers default
	to text mode in general.

	If you are editing these files simply search for 'fopen' and alter the 
	"w" to "wb", "r" to"rb" and "w" to "wb+"

Step 4
	Compile all 12 files to object files using the following example 
	command line. 

		GCC -O -c chendct.c

	Ignore the warnings from the compiler about implicit definitions etc.

Step 5
	Link all the files together to form PVRGMPEG

	gcc lexer.o mpeg.o huffman.o transfor.o codec.o io.o marker.o
		 me.o mem.o stat.o stream.o chendct.o  -lgcc -lm -o pvrgmpeg
	
	Note all one line 

Step 6 
	Create PVRGMPEG.EXE

	copy /b \gcc\bin\go32.exe+pvrgmpeg pvrgmpeg.exe

		 ^^^^^ alter path to suit!


Step 8
	Use and enjoy.
