"	      for Amiga:  s:.vimrc
"  for MS-DOS and Win32:  $VIM\_vimrc
"	    for OpenVMS:  sys$login:.vimrc

" When started as "evim", evim.vim will already have done these settings.

" Use Vim settings, rather than Vi settings (much better!).
" This must be first, because it changes other options as a side effect.
