set autoread " When a file has been detected to have been changed outside of Vim and

set smarttab " a <Tab> in front of a line inserts blanks according to
"              'shiftwidth'.  'tabstop' or 'softtabstop' is used in other places
set shiftwidth=4 " Number of spaces to use for each step of (auto)indent.
set tabstop=4 " Number of spaces that a <Tab> in the file counts for.
set softtabstop=4  " Number of spaces that a <Tab> counts for while performing editing
"                    operations, like inserting a <Tab> or using <BS>.
set autoindent " Copy indent from current line when starting a new line
set expandtab " In Insert mode: Use the appropriate number of spaces to insert a
"               <Tab>.  Spaces are used in indents with the '>' and '<' commands and
"               when 'autoindent' is on.  To insert a real tab when 'expandtab' is
"               on, use CTRL-V<Tab>
"               Set 'tabstop' and 'shiftwidth' to whatever you prefer and use
"               'expandtab'.  This way you will always insert spaces.  The
"               formatting will never be messed up when 'tabstop' is changed.
set smartindent " Do smart autoindenting when starting a new line.  Works for C-like
"                 programs, but can also be used for other languages.  'cindent' does
"                 something like this, works better in most cases, but is more strict
