" This is a 'literate vimrc', in the Donald Knuth tradition.  It's long, and
" comments abound.
"
" This file should be saved as "vimrc" in the user runtime directory. (UNIX
" ~/.vim, Windows ~/vimfiles).  It requires Vim 7.0 or newer with +eval, not
" running in &compatible mode.  The vimrc stub (UNIX ~/.vimrc, Windows
" ~/_vimrc) that loads this file checks that these two conditions are met.
"
" > And I was lifted up in heart, and thought

" > How my strong lance had beaten down the knights,
" > So many and famous names; and never yet
" > Had heaven appeared so blue, nor earth so green,
" > For all my blood danced in me, and I knew
" > That I should light upon the Holy Grail.

" Set an environment variable MYVIM for the user runtime directory, if such
" a variable does not already exist in the environment, and there's a value in
" 'runtimepath' from which to glean a useable path.  We'll use the path
" nominated in the MYVIM variable as the root of our 'backupdir', 'directory',
" 'undodir', and 'viminfofile' caches.
"
" I think the absence of a variable like this is a glaring omission from Vim.
" We have $VIM, $VIMRUNTIME, and $MYVIMRC, so why is there not an environment
" variable for the first runtime directory?  It's a mystery, and that's why so
" is mankind.

"
" In general, however, I prefer spaces to tabs as a default, and I like to use

" back as v5.8.0 (2001), and 'undodir' appears to have supported it since its
" creation in v7.2.438.  Even though the :help for 'backupdir' didn't say so,
" people assumed it would work the same way, when in fact Vim simply ignored
" it until v8.1.251.
"
" I don't want to add the slashes to the option value in older versions of Vim
" where they don't do anything, so I check the version before I add them.
