# sdlBasic is a little basic for make simple games in 2d
#
# This basic run on :
# linux(with a reasonable recent version)
# windows (9x and nt-XP based)
# macOSX
# FreeBSD
# OpenBSD
# MorphOS
# AmigaOS
#
# This basic is another demostration to the GPL's power
# the basic interpreter come from wxbasic by David Cuny
("http://wxbasic.sourceforge.net") distribuited under lGPL
# The graphic system is based uppon SDL graphics libraries family
("http://www.libsdl.org")distribuited under GPL
# The graphics engine was initially based on the aliens demo game
("http://www.libsdl.org/projects/aliens")
# written in c and distribuited on GPL, later graphic engine was re-written from
scratch.
# putpixel and getpixel routines are derivated from SDL tutorial and was improved
with Gigi Davassi suggestions
# The original line rutine was imported from Alvyn Basic with Author's write
permission.
# I used also the source of sdldraw library ("http://sdl-draw.sourceforge.net/") ever
lGPL
#
# I cut, pasted and adapted code distribuited under lGPL.
# This software is subject to lGPL license and is free as every program used to
create it
