Patch from Lucas Rocha <lucasr@im.ufba.br> to use the GOption
API for the zenity parsing options, with some spacing fixes

* src/Makefile.am, src/gdialog: Compatibility wrapper script
from Mike Newman <mikegtn@gnome.org>. Disabled for the present
until I have a chance to review the code.
2003-01-14 Glynn Foster <glynn.foster@sun.com>
* Makefile.am, src/Makefile.am: Updates to make
distcheck. Wow, this is scarey, a 1.0 release is on the
horizon. Applications like this shouldn't reach 1.0.
2003-01-14 Glynn Foster <glynn.foster@sun.com>
* src/Makefile.am, src/about.c, src/main.c,
src/zenity.glade: Add an about box. Still need to add
an icon, and implement the callbacks for Help and Credits. Extra
hassle for not linking against libgnomeui. Sigh.
