The X2 Editor was derived from Tim Baldwin's XE sample
editor. Extensive
modifications have been made to the functionality and internal workings of
the editor, but the author is indebted to Tim for sharing the original source
code.
In functionality X2 derives from the E family of editors, E3 and EOS2 in
particular. The authors of these editors are
Clark Maurer, Bryan Lewis, Jean Christophe
Bandini, Richard Redpath, Davis Foulger, and
Larry Margolis. E in turn was influenced by Personal Editor, by
Jim Wyllie.
X2 also includes some features from VM's XEDIT editor. XEDIT was
originally written by Xavier de Lamberterie.
The Unix versions make use of X-Windows routines, most of which are
taken from Scott Schaffer's VE editor.
There have been dozens of people who have contributed ideas, macros,
encouragement, and of course bug reports. I can't name you all, but I am
very grateful for the interest you have shown in this project.
