RText is a powerful, cross-platform programmer's text editor written in Java. It is designed
to be easy to use, highly customizable and flexible. Part of RText's design is for the source code
to be simple, easy to understand, and well documented, so that other programmers can look into its
inner-workings and figure out how RText ticks with ease. A good place to start (besides the source
code) is the Javadoc for all classes used in the project.
