Starting Vim arguments

-S {file} The {file} will be sourced after the first file has been read. This is an easy way to do the equivalent of: -c “source {file}” It can be mixed with “-c” arguments and repeated like “-c”. The limit of 10 “-c” arguments applies here as well. {file} cannot start with a ”-“.

	Do not use this for running a script to do some work and exit
	Vim, you won't see error messages.  Use -u instead.

-u {vimrc} The file {vimrc} is read for initializations. Most other initializations are skipped; see initialization.

	This can be used to start Vim in a special mode, with special
	mappings and settings.  A shell alias can be used to make
	this easy to use.  For example: 
		alias vimc vim -u ~/.c_vimrc !*
	Also consider using autocommands; see autocommand.

	When {vimrc} is equal to "NONE" (all uppercase), all
	initializations from files and environment variables are
	skipped, including reading the gvimrc file when the GUI
	starts.  Loading plugins is also skipped.

	When {vimrc} is equal to "NORC" (all uppercase), this has the
	same effect as "NONE", but loading plugins is not skipped.

	When {vimrc} is equal to "DEFAULTS" (all uppercase), this has
	the same effect as "NONE", but the defaults.vim script is
	loaded, which will also set 'nocompatible'.  Also see
	--clean.

	Using the "-u" argument with another argument than DEFAULTS
	has the side effect that the 'compatible' option will be on by
	default.  This can have unexpected effects.  See
	'compatible'.
