------------------
* Allow command-line choices for what files to build, and what languages ctags
should parse. (Note that the default behavior of running ``./bin/tags``
is the same as previous releases.)
* Support the Mac OS X packaging system "macports" (exuberant ctags is
``ctags-exuberant`` in Ubuntu and ``ctags`` in macports).
* Support creating BBEdit-style ctags files.
* Small changes for development (use bootstrap external, set svn:ignore)
