/** \class ctags2
This is a CTAGS frontend based on the 'readtags' library.
\authors Jens Dagerbo
\maintainer Jens Dagerbo
\feature A very fast CTAGS lookup plugin
\feature Through the use of regular expressions, it is clever enough to find matches even
if the match-containing file is open and edited (and the editor contents do not match the file on disk).
\requirement Needs "Exuberant CTAGS" to work. http://ctags.sourceforge.net/
\todo Probably a lot, but mainly configurability.
