"  matchit.vim: (global plugin) Extended "%" matching
"  Maintainer:  Christian Brabandt
"  Version:     1.18
"  Last Change: 2020 Dec 23
"  Repository:  https://github.com/chrisbra/matchit
"  Previous URL:http://www.vim.org/script.php?script_id=39
"  Previous Maintainer:  Benji Fisher PhD   <benji@member.AMS.org>

" Documentation:
"  The documentation is in a separate file: ../doc/matchit.txt

" Credits:
"  Vim editor by Bram Moolenaar (Thanks, Bram!)
"  Original script and design by Raul Segura Acevedo
"  Support for comments by Douglas Potts
"  Support for back references and other improvements by Benji Fisher
"  Support for many languages by Johannes Zellner
"  Suggestions for improvement, bug reports, and support for additional
"  languages by Jordi-Albert Batalla, Neil Bird, Servatius Brandt, Mark
"  Collett, Stephen Wall, Dany St-Amant, Yuheng Xie, and Johannes Zellner.

" Debugging:
"  If you'd like to try the built-in debugging commands...
"   :MatchDebug      to activate debugging for the current buffer
"  This saves the values of several key script variables as buffer-local
"  variables.  See the MatchDebug() function, below, for details.

" TODO:  I should think about multi-line patterns for b:match_words.
"   This would require an option:  how many lines to scan (default 1).
"   This would be useful for Python, maybe also for *ML.
" TODO:  Maybe I should add a menu so that people will actually use some of
"   the features that I have implemented.
" TODO:  Eliminate the MultiMatch function.  Add yet another argument to
"   Match_wrapper() instead.
" TODO:  Allow :let b:match_words = '\(\(foo\)\(bar\)\):\3\2:end\1'
" TODO:  Make backrefs safer by using '\V' (very no-magic).
" TODO:  Add a level of indirection, so that custom % scripts can use my
"   work but extend it.

" Allow user to prevent loading and prevent duplicate loading.
