GDIT
====

Simple Graphics Interpreter.

Windows 95 / NT version.  Refer to documentation index.htm

Release notes for version 1.4, based on version 1.2 of gd library.

GDIT is built from the UNIX source using MSVC 2.0.  The GNU tools:
flex and bison were used to generate the interpreter.  To rebuild
you will need to run these by hand:

	flex lexer
	bison grammar
	mv grammar.tab.c grammar.c

This should be done in the src directory.  There is an MSVC 2.0
makefile, gdit.mak in this directory.  This will rebuild gdit, don't
worry about warnings, these concern prototypes.

Note there is some problem with the interpreter where the input line
is not terminated by <CRLF> for the first few commands.  This appears
to be an artifact of the Windows environment and I have been unable
to locate the problem.  You have to hit RETURN as second time
to get the prompt back.  This does not affect the operation of the
scripts.

The two demo programs were written for a NeXT system running BSD UNIX.
The color sampler should work under NT but 3.5.1.

If you have an interesting application which uses GDIT why not tell me
about it?


TESTING GDIT
============

The sub-directory tests contains a set of gdt files with test scripts.
Run these:

        gdit -f <testfile>.gdt

You should see a series of '>' printed to the screen for each test line.
A GIF file should be produced.
