# This is not an automatic gtk+-1.x to gtk+-2.x port tool,
# just a tool that ease perl apps' gtk2 port.
# you'll have to fix all remaining problems, beginning by spotted warnings
# it'll save you basic conversion work
#
# if you used Gtk::Text, a little more work will be needed (look at logdrake gtk2 port)
# if you used Gtk::CTree, Gtk::CList or worse, Gtk::Tree, you'll need quite a lot of exhausting work :-(
#
# usage: porting-ugtk <file>
#
# hint: always use strict

# switch to gtk2 :
s!Gtk:!Gtk2:!g;

s!my_gtk!ugtk2!g;

# one should pass the right ":stuff" to "use ugtk2 qw();"
/ugtk::/ and print STDERR "Warning: you'll have to passe eiter :ask, :create, :helpers or :wrappers to ugtk\n";
