Addition to wiki

[Joe Mason]

Hi,

I want to add a simple tool to
http://wiki.gnustep.org/index.php/Writing_portable_code.  It says:

  FIXME: add following:
  how to convert Xcode project to GNUstep project (creating a GNUstep
Makefile
<http://www.gnustep.it/nicola/Tutorials/WritingMakefiles/index.html> or
ProjectCenter <http://wiki.gnustep.org/index.php/ProjectCenter>

PBTOMAKE
(http://www.macdevcenter.com/pub/a/mac/2004/04/20/xcodetounix.html,
download at http://members.bellatlantic.net/%7Evze35xda/software.html)
is a tool for converting Xcode and Project Builder files to generic Unix
Makefiles.  It would probably be a good start for converting to a
GNUstep makefile, and should be mentioned on that page.
