Just go to the root directory and un-tar this archive.  The binary will go
to /usr/X386/bin, the man page will go to /usr/man/man1, and the rest of
the files will go to /usr/X386/bin/fractint.

The binary is compressed with gzexe, but since this archive is compressed
with gzip, you are already able to run it. [How else could you have
extracted the archive?]

The binary and the man page can go wherever you normally put yours, but the
"extra" files need to be at /usr/X386/bin/fractint, since that is where I
told them to be in the Makefile when I compiled it.  But if they are not
in that location, I believe that the program will also look in the current
directory for them.

If you think my arrangement completely sucks, then you can always recompile
it from the source yourself:  ftp to sprite.berkeley.edu, and pick up the
xfract* files.  The one change you need to make to the code to make it
compile on Linux is in unixscr.c:  Change all references to "FNDELAY" to
be "O_NDELAY".  I mailed the keeper of the source code about this which can
be easily fixed so that Linux people can just add -DLINUX to the CFLAGS, 
but until he gets around to it you will have to do it by hand.

Happy fractaling!
