- either adding to your `:help vimrc`
if has('clientserver') && empty(v:servername) try call remote_startserver('VIM-' . getpid()) catch '^Vim\%((\a\+)\)\=:E\%(941\|240\)' endtry endif
- or, at least on Unix, calling vim by, say `$HOME/bin/vim` with `$HOME/bin` in `$PATH` and launching
/usr/bin/vim --servername vim -u ~/.vim/vimrc "$@"
