[XeTeX] listing support for teckit map files

[Daniel Greenhoe]

Does any one know of any listing support for teckit map files?

Currently I use the listings package:
  https://ctan.org/pkg/listings
It does support TeX as a language and LaTeX as an option as in
  \lstset{language=[LaTeX]TeX}
However, LaTeX syntax and teckit map syntax are quite different.
For example, a comment in LaTeX begins with %,
whereas in a teckit map a comment begins with ;

Teckit is one of the best developments since sliced bread, so it would
be a pity not to be able to properly list teckit map source in a TeX
document.

Many many thanks in advance,
Dan
