FreonLinux/system/rxvt/README.configure

--enable-everything
	add support for all enable options marked with an asterisk listed
	in "./configure --help".  Note that unlike other enable options this
	is order dependant.  You can specify this and then disable options
	which this enables by _following_ this with the appropriate
	commands.
--enable-languages
	add support for languages which require multiple character glyphs
	to display.
--with-encoding=NAME
	set the default encoding for multi-char glyph languages to NAME.
	Options are: "eucj" EUC Japanese encoding; "sjis" Shift JIS encoding;
	"big5" BIG5 encoding; "gb" GB encoding; "kr" EUC Korean encoding;
	"noenc" no encoding.  This option requires --enable-languages to
	also be specified.
--enable-utmp
	write user and tty to utmp file (used by programs like ``w'') at
	start of rxvt execution and delete information when rxvt exits.
--enable-wtmp
	write user and tty to wtmp file (used by programs like ``last'') at
	start of rxvt execution and write logout when rxvt exits.  This
	option requires --enable-utmp to also be specified.
--enable-lastlog
	write user and tty to lastlog file (used by programs like
	``lastlogin'') at start of rxvt execution.  This option requires
	--enable-utmp to also be specified.
--enable-xpm-background
 	add support for XPM background pixmaps
--enable-transparency
	add support for inheriting parent backgrounds thus giving a fake
	transparency to the term
--enable-menubar
	add support for our menu bar system
--enable-graphics

--enable-half-shadow
	make shadows on the scrollbar only half the normal width & height.
	only applicable to rxvt scrollbars
--enable-xim

	set up the input for people using dead keys.
--enable-greek

--enable-ttygid
	change tty device setting to group "tty" - only use this if
        your system uses this type of security

	do it
--disable-resources

--enable-xgetdefault

	version which only checks ~/.Xdefaults, or if that doesn't exist
	then ~/.Xresources
--enable-strings
	add support for our possibly faster memset() function and other
	various routines, overriding your system's versions which may
	have been hand-crafted in assembly or may require extra libraries
	to link in.  (This has header problems on some Linux systems).
--disable-swapscreen
	remove support for swap screen
--enable-frills
	add support for some lesser used features
--enable-linespace
	add support to provide user specified line spacing between text rows

	remove support for mouse selection style like that of xterm
--enable-dmalloc
	use Gray Watson's malloc - which is good for debugging
	See  http://www.letters.com/dmalloc/  for details
        If you use either this or the next option, you may need to
	edit src/Makefile after compiling to point DINCLUDE and DLIB to
	the right places.
        You can only use either this option and the following (should
	you use either) 
--enable-dlmalloc
	use Doug Lea's malloc - which is good for a production version
	See  http://g.oswego.edu/dl/html/malloc.html  for details
--enable-smart-resize

	via from hot keys.  This should keep in a fixed position the
	rxvt corner which is closest to a corner of the screen

--with-term=NAME
	change the environmental variable for the terminal to NAME
	(default "xterm")
--with-terminfo=PATH
	change the environmental variable for the path to the terminfo
	tree to PATH
--with-x
	use the X Window System (pretty much default, eh?)
--with-xpm-includes=DIR
	look for the XPM includes in DIR
--with-xpm-library=DIR
	look for the XPM library in DIR
--with-xpm
