GStreamer uses a *large* array of tools and libraries, most of which are

optional.  We have attempted to make sure that any code that depends on

optional libraries doesn't get built unless you have those libraries.  If

you find this not to be the case, please, let us know by filing a bug

report at http://bugzilla.gnome.org/.

Required tools:

===============

An extra set of tools is required if you wish to build GStreamer out of

git (using autogen.sh):

autoconf 2.52 or better 

automake 1.5

gettext 0.11.5

libtool v1.4 or better

pkgconfig 0.9.0 or better (http://www.freedesktop.org/software/pkgconfig/)

Required libraries:

===================

The core GStreamer libraries. See the gstreamer/ module in GStreamer cvs, or

the version that corresponds to this plugin release.

Optional libraries:

===================

This file lists supporting libraries for which gst-plugins contains plugins,

as well as their minimum version.  You can find the corresponding plugins in
