i'll volunteer to be maintainer of Java and Ruby support, and at least
reviewer of C++ and Make patches.
i've also mentioned some interest in adding LaTeX in the past, and in
improving HTML support to include the various levels of heading.
my main interest in Exuberant ctags is that my editor,
http://software.jessies.org/Evergreen/ uses it (if available) to present a
hierarchical clickable "table of contents" for whatever you're working on.
(there's an out-of-date screenshot on that page showing a small Java
example.) so i have a passing interest even in languages i don't use.
