+# gdialog -> zenity conversion wrapper

+# by Mike Newman <mikegtn@gnome.org>

+# This is all, of course, horrible - but it should translate
+# most commond gdialog types to zenity equivalents. It will drop
+# the pointless and unused (even by gdialog!) size arguments
+# but hopefully will pass all the others.
+#
+# For testing purposes, I've used a couple of the nautilus scripts
+# available at http://g-scripts.sourceforge.net - what is sometimes
+# unclear is what is a gdialog/zenity translation problem, and what is
+# a problem with the script
