Exuberant-ctags allows a user to add a new parser to ctags with --langdef=<LANG> and --regex-<LANG>=... options.

Universal-ctags follows and extends the design of Exuberant-ctags in more powerful ways, as described in the following chapters.

Universal-ctags encourages users to share the new parsers defined by their options. See :ref:`optlib <optlib>` to know how you can share your parser definition with others.

Note that some of the new features are experimental, and will be marked as such in the documentation.
