It has been a long time, but here's another release. This one is nothing spectacular; most changes and improvements are internal and not visible to a user. I started to use the Boost libraries. The compiler and highlighter programs now use Boost's program_options library for parsing command-line parameters.
The lack of interesting new features in the front end is because I have worked on the back end as well. This work is in a very premature state, so you won't see a full compiler anytime soon.
