<para>Writing of <application>BitBake</application> recipes is easier
and more intuitive than writing Makefiles while providing higher
flexibility. This allows you to tweak specific recipes for your very
special needs and to add new recipes quickly. You can build toolchains,
Software Distribution Kits (SDKs), complete Distributions or just single
packages. The flexibility of OpenEmbedded allows you to reuse recipes
for many different purposes. OpenEmbedded provides
everything buildroot will be able to provide. But in contrast to buildroot
OpenEmbedded will allow you to achieve what you really want to achieve.
You can add new package formats, new filesystems, new output formats
easily. OpenEmbedded will suit your need.</para>

<para>Crosstool allows the creation of toolchains. It can only create
the initial toolchain for you. It will not compile other needed libraries
or applications for you, it will not be able to track dependencies or
package them properly. OpenEmbedded supports all configurations crosstool
supports. You can start by creating toolchains with OpenEmbedded, then as
your needs grow create a more complete SDK from already present base
libraries and applications and if you recognize you need to have packages
for the target you have them almost built already.</para>

<para>Cross-compilation is a tough business. It is not that
cross-compiling is hard itself but many people misuse the buildsystem they
use to build their software. This will lead to a variety of issues you can
run into. This can be failing tests on configuration because of executing
cross compiled binaries or crashes at run-time due to wrong sizes of basic
types. When utilizing OpenEmbedded you avoid searching for patches at many
different places and will be able to get things done more quickly.
<application>OpenEmbedded</application> allows you to choose from a pool
of ready to use software packages.</para>
<para>OpenEmbedded will create complete flashable images using different
output formats and filesystems. This allows you to create complete and
specialized distributions easily.</para>
