Acidwarp for Linux 1.0 by Steven Wills

This is the Linux SVGAlib port, downloaded from:
http://sunsite.unc.edu/pub/Linux/apps/graphics/hacks/svgalib/acidwarp-1.0.tar.gz

All object files (*.o), the x86 binary acidwarp, and the backup
file acidwarp.c~ have been deleted. Line endings in handy.h and
lut.h have been converted from DOS to Unix. There are no other
changes.

Original MS-DOS Acidwarp 4.10 by Noah Spurrier and Mark Bilk

These are the contents of http://www.noah.org/acidwarp/acidwarp.zip
with only changes being lowercased filenames and Unix line endings.
Line endings in vc++70.mak were not converted because that file is
for DOS only.

The original unaltered acidwarp.exe binary is included. It was
built with an old proprietary compiler, and this source may not
build with any modern toolchain. The binary can run in DOSBox or
other emulators.

SDL port by Boris Gjenero

This is an SDL port based on the XFCE port. It is functional, but
the Makefile is for cross-compiling a Windows binary from Cygwin.
