The files in this folder define syntax highlighting for various languages. Any XML file added here, defining the syntax highlighting of a language, will be automattically added in C::B.
Look at the existing files. Their syntax is quite straightforward. The only thing that needs clarification is the "index" attribute.
In the <Lexer> element, the "index" attribute denotes the index of the scintilla lexer to be used. These are the wxSTC_LEX_* macros in stc.h (don't use macros - use the index number).
In the <Style> element, the "index" attribute is the style index. It's the wxSTC_[lang]* (e.g. for c/cpp it's wxSTCC_*). You can use more than one index (comma separated) in a style. This groups many styles under a single configuration option (like single line comments, multi-line comments, etc under one "comments" option).
