nengel@7: % This is something that non-hacker-type \LaTeX users have needed for
nengel@7: % a long time.  It's just really stupid to have to explain how all of
nengel@7: % the page dimensions work, and how to use \setlength and \addtolength
nengel@7: % to change them, evey time someone who doesn't really care about it
nengel@7: % wants to change their margins.  This file gives them the ability to
nengel@7: % do that easily.
nengel@7: %
nengel@7: % \setleftmargin{dimen} sets the left margin to that width
nengel@7: % \setrightmargin{dimen} sets the right margin to that width
nengel@7: % \settopmargin{dimen} sets the top margin to that width
nengel@7: % \setbottommargin{dimen} sets the bottommargin to that width
nengel@7: % \setallmargins{dimen} sets all four margins to that width
nengel@7: % 
nengel@7: % \setpagewidth{dimen} sets the page width to that width
nengel@7: % \setpageheight{dimen} sets the page height to that width
nengel@7: % 
nengel@7: % The page is assumed to be 8.5 x 11 when this file is initially
nengel@7: % loaded.  If this is not the case, then use
nengel@7: % 
nengel@7: % 	\setlength{\smpagewidth}{dimen}
nengel@7: %	\setlength{\smpageheight}{dimen}
nengel@7: % 
nengel@7: % after loading simplemargins to set the actual page width and height,
nengel@7: % before using any of the other simplemargins command (*including*
nengel@7: % \setpagewidth or \setpageheight, which depend on the previous values
nengel@7: % for \smpagewidth and \smpageheight).
