I'm working with a very large code base and I find it useful to be selective about which directories are included for use with Exuberant Ctags.
The --exclude option works well to eliminate individual file and directory names (with globing wildcards), but I can't figure out how to get it to exclude path patterns containing more than one directory.
For example, I may want to exclude a directory tests, but only when processing thirdparty\tests (under Windows). The problem is if I just use --exclude=tests I exclude too many directories, including a test directory in the code I'm actively working on.
Here are some things I've tried:
--exclude=thirdparty\tests
--exclude=thirdparty\\tests
--exclude=*\thirdparty\tests
--exclude=*\\thirdparty\\tests
--exclude=thirdparty/tests
Ctags silently ignores all these as evidenced by an examination of the tags file.
How can I exclude a directory only when it is preceded by a given parent directory?

Here's my ctags --version output:

At some point it might be easier to define the list of files you do want indexed; save that list to a file, and use ctags -L <filename> to index just the chosen few.
This lets you use find(1) to prune the directories you don't want to index, e.g.:
find . -path ./Documentation -prune -o -print > indexme
would skip all the files in all subdirectories of ./Documentation.
