Excalibur is a Macintosh spelling checker for LaTeX documents. It also does a fairly good job with plain TeX files. It reads files of type TEXT and it is smart enough to ignore most LaTeX commands and a fair number of plain TeX commands. Since it just ignores these commands, it will also serve quite nicely as a spelling checker for any TEXT file that doesn't contain any LaTeX or TeX commands. (It is not completely accurate to say that Excalibur ignores LaTeX commands. It will process any arguments that contain text).
Excalibur is a stand-alone application that we have tested with both OzTeX and Textures documents. The fact that it is a stand-alone application should not present any inconvenience since it works with MultiFinder under System 6 and it is compatible with System 7.
This is version 1.1. It is a significant improvement over version 1.0.
You will need System 6.0 or higher to run Excalibur.
There is extensive on-line help. You will find it under the Apple menu if you are running System 6, and under the Balloon Help menu if you are running System 7 or greater.
