Excalibur's LaTeX Philosophy

One approach to LaTeX spell checking is to put all the commands into the dictionary. This yields limited success because it does not specify what should be done with the arguments of the commands. For example, the \label command has an argument that should always be ignored. On the other hand, the \section command has an argument that should always be spell checked. To complicate things more, there are commands such as \addtocontents that have one argument that should be ignored, and another that should be spell checked.

Excalibur does not put LaTeX commands into its dictionary. Instead, it knows how to process each command intelligently. It knows which arguments to ignore and which it should spell check. As a result, Excalibur is a LaTeX spelling checker that does a very good job.
