Thank you for trying out BGI Library for Linux from G & Y Systems.

The library provides full sources compatibility with Borland(TM) BGI
graphical layer, and allows one to port graphical applications written
with Borland C/C++ compilers to Linux.

The library contains over 65 various functions that allow one to draw
lines, rectangles, polygons, control viewports, paint 2d and 3d bars,
and perform other graphical operations.

You are encouraged to read the accompanying exerpts from the manual
and the licensing agreement prior to using the library.

This distribution contains a shareware version of the library and
several demonstration programs.

To install the library and the header file in the appropriate
directories, you should su to root, and type the following command:

	$ make install

This command will copy graphics.h to /usr/include directory, and
libBGISm.a, the library, to /usr/lib directory. 

You should now be able to start using the library, just as you would
any other library on you Linux system.  

You migth want to examine the makefile, it contains an example of how
a program using the BGI library can be built.

Three demo programs are contained in this distribution.  

The first program, demo, shows the capabilities of the shareware
version of the library.  It can be invoked with the following
command-line arguments:

	/G640x200x16
        /G640x350x16
   	/G640x480x16
        /GRAPHMONO

Each argument specifies the graphical resolution at which the demo
program will be run.  Note that the program attempts to automatically
detect adapter type, and defaults to standard VGA resolution,
/G640x480x16 if it determines that the specified argument is not
compatible with the available adapter.

To start the demo in CGA mode, you can use the following command:

	$ demo /G640x200x16

The second program, demo_fast, is exactly the same as the previous
one, but has been linked with the commercial version of the library.
It supports additional command-line arguments that allow to run the
demo in SVGA modes.  The following command-line arguments are
available for demo-fast:

	/G640x200x16
        /G640x350x16
        /G640x480x16
        /G320x200x256
	/G800x600x16
	/G1024x768x16
 	/G640x400x256
	/G640x480x256
	/G800x600x256
	/G1024x768x256
	/GRAPHMONO

The same limitation applies to demo_fast as to demo -- specified
graphics mode will be accepted as long as it does not contradict what
has been detected by the library.  You should be able to see the
improvement in performance in all the areas of the demo.

The third demo program, mstest, is a sample mouse demo program.
Presently, it supports only Microsoft(TM) 2-button mouse or
compatible.  It accepts the same command-line arguments as demo_test,
and can run in SVGA mode on supported adapters.

Demos and the library have been built with GCC 2.6.3 on Linux 1.2.2,
installed from Slackware distribution 2.1.

If you experience incompatibility problems with earlier versions of
Linux, please contact G & Y Systems, and we will attempt to resolve
your problems.
