This customizable XHTML editor works like a word processor the control codes of which are the XML markup. Of course, the user interface is English, too.

The working mode is neither WYSIWYG nor source hacking but WYSIWYM (what you see is what you mean; this expression is not my copyright, but matches.)

To install, just download and unzip the zip file and after first start, switch to the desired language (menu Spezialwerkzeug – Einstellungen – Sprache – Englisch or menu Tools – Preferences – Language – German). Actually, the supported OS is Windows.
The editor is freely downloadable. The usage is without fee.
The professional version intended for productive usage contains support. There is an interface to Schematext. It does'nt matter the private user. More customizing is possible on request.

Programming language Tcl/Tk used (showing and hiding tags and graphics is not coded but just switched by Tcl/Tk commands).
Tcl/Tk runs slower than a C program; for working, a Pentium 200 is necessary. The benefit is that this editor was just possible. For scripting languages are more productive than C. Developping .mte. from the sketch didn't take more than a year—inclusive getting Tcl/Tk basic knowledge.
.mte. is designed as an XML editor. It cannot tolerate erraneous HTML code. For reading in old-fashioned documents, the syntax checker Tidy by Dave Ragget is used (contained in the download).
For generating the executable file, the Wrapper Freewrap is used.
For display of the Web graphics formats JPG und PNG, the package IMG by Jan Nijtmans is used (contained in the download).
The development tools are GNU Emacs V. 20.4.1 and Source-Navigator V. 4.5.2 by Red Hat.
Graphics is made with Macromedia Fireworks.
The help system is made with Schematext V. 2.17; the external editor was .mte. (sic! By the way, it was a breeze.)
