To compile fractile with support for X11, just give the command "make".
Nothing fancy is required.

To compile it without X11 support (so it can only generate a GIF file),
you must edit the Makefile and change the values of the LIBS and CFLAGS
lines as follows:

	LIBS=	-lm
	CFLAGS=

You can then copy the "fractile" executable to /usr/local/bin, and the
"fractile.man" man page to /usr/local/man/man1, or wherever.

To create the example GIFs mentioned in the man page, just give the
command "make examples".  You should do this before running Netscape on
the "examples.html" file because that file has links to the GIF images.
