Wrapper headers, M4 macros, configuration scripts, and library
symlinks, which simulate the presence of GLib1, GTK+1, GDK-Pixbuf1, and
libglade1 development packages, but use GLib2, GTK+2, and libglade2.
Using it, you can force to link some older applications with new
libraries without any effort.

The package also provides the gtk1-compat-autofix script, which does
some source code modifications that cannot be worked around any other
way, and a static library with some obsolete functions.
