+-- (1.0) What is Tetradraw
Tetradraw is a full featured ANSI art editor for *nix operating systems. ANSI art is an art made only of the ASCII characters and coloured with 16 colours. ANSI arts main use is in text mode interfaces. Tetradraw is the first completly usable ANSI art editor for *nix operating systems. However Tetradraw does not only emulate the ansi editors for DOS. Tetradraw is a revolution in the way ANSI art can be drawn, for the first time ever two artists can draw together over the internet on the exact same image (MultiDraw). This has been a long awaited feature and should provide a new level of art.
On top of the ground breaking MultiDraw here are some of Tetradraw's features:
+-- (1.1) System Requirments
A Unix System (Has been tested on Linux) A Console capable of text colour graphics. Ncurses 5.0 gcc or compatable ANSI C compiler.

Tetradraw and all of its source code is licensed under the GPL. The artwork is owned by the artists. A copy of the GPL
should be included in the distribution with the filename COPYING.

There are two different installations that you can do depending on the format you download tetradraw in.
+-- (2.1) Installation from souce code:
If you download the source tarball then you will follow these instructions.
You should recieve tetradraw in the form of tetradraw-version.tar.gz where version is the numerical version code of the copy you recieved.
Steps to install:
bash$ tar zxvf tetradraw-version.tar.gz
bash$ cd tetradraw-version
You can then copy the tetradraw and tetraview binaries from the src directory to wherever you would like to use them.
Or you can do this and install them globally on your system:
bash# make install
+-- (2.2) Binary Installation
If you recieved tetradraw as a binary you should follow these insructions.
You should have recieved 2 gzipped files
where version is the numerical version code of the copy you recieved.
