+# 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 mostly drop
+# the pointless and unused (even by gdialog!) size arguments
+# but hopefully will translate 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 original script

+# gdialog itself supports both the X-Windows interface as well as a console
+# interface. Here's a fix to use regular dialog when appropriate.
+# This should probably be a more advanced test of some sort, but I don't know
+# of any other easy way of detecting and X-Windows environment. If someone does
+# know better, please let me know. So for now this works: "no DISPLAY; no X".
