-GTK+ requires the following packages:
-
- - Autotools or Meson
-
- - The GLib, Pango, GdkPixbuf, ATK and cairo libraries, available at
-   the same location as GTK+. GTK+ @GTK_VERSION@ requires at least
-   GLib @GLIB_REQUIRED_VERSION@, Pango @PANGO_REQUIRED_VERSION@,
-   GdkPixbuf @GDK_PIXBUF_REQUIRED_VERSION@, ATK @ATK_REQUIRED_VERSION@
-   and cairo @CAIRO_REQUIRED_VERSION@.
-
- - libepoxy, for cross-platform OpenGL support.
-   It can be found here: https://github.com/anholt/libepoxy
-
- - Each GDK backend has its own backend-specific requirements. For
-   the X11 backend, X11 R6 and XInput version 2 (as well as a number
-   of other extensions) are required. The Wayland backend requires
-   (obviously) the Wayland libraries.
-
- - gobject-introspection @INTROSPECTION_REQUIRED_VERSION@ or newer.
-
-Simple install procedure for Meson
-==================================
-
-  % tar xf gtk+-@GTK_VERSION@.tar.xz          # unpack the sources
-  % cd gtk+-@GTK_VERSION@                     # change to the toplevel directory
-  % meson setup _build                        # configure GTK+
-  % meson compile -C _build                   # build GTK+
-  [ Become root if necessary ]
-  % meson install -C _build                   # install GTK+
-
-Simple install procedure for Autotools
-======================================
-
-  % tar xf gtk+-@GTK_VERSION@.tar.xz          # unpack the sources
-  % cd gtk+-@GTK_VERSION@                     # change to the toplevel directory
-  % ./autogen.sh                              # configure GTK+
-  % make                                      # build GTK+
