Changing the folder that holds the YP Reference Manual to be "ref-manual". This will help with confustion over the manual's intended purpose.

The BitBake task executor together with various types of configuration files form the
|
||
OpenEmbedded Core.
|
||
This section overviews the BitBake task executor and the
|
||
configuration files by describing what they are used for and how they interact.
|
||
</p>
|
||
<p>
|
||
BitBake handles the parsing and execution of the data files.
|
||
The data itself is of various types:
|
||
</p>
|
||
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
|
||
<li class="listitem"><p><span class="emphasis"><em>Recipes:</em></span> Provides details about particular
|
||
pieces of software</p></li>
|
||
<li class="listitem"><p><span class="emphasis"><em>Class Data:</em></span> An abstraction of common build
|
||
information (e.g. how to build a Linux kernel).</p></li>
|
||
<li class="listitem"><p><span class="emphasis"><em>Configuration Data:</em></span> Defines machine-specific settings,
|
||
policy decisions, etc.
|
||
Configuration data acts as the glue to bind everything together.</p></li>
|
||
</ul></div>
|
||
<p>
|
||
For more information on data, see the
|
||
"<a class="link" href="../dev-manual/yocto-project-terms.html" target="_self">Yocto Project Terms</a>"
|
||
section in the Yocto Project Development Manual.
|
||
</p>
|
||
<p>
|
||
BitBake knows how to combine multiple data sources together and refers to each data source
|
||
as a layer.
|
||
For information on layers, see the
|
||
"<a class="link" href="../dev-manual/understanding-and-creating-layers.html" target="_self">Understanding and
|
||
Creating Layers</a>" section of the Yocto Project Development Manual.
|
||
</p>
|
||
<p>
|
||
Following are some brief details on these core components.
|
||
For more detailed information on these components see the
|
||
"<a class="link" href="ref-structure.html" title="Chapter 5. Source Directory Structure">Directory Structure</a>" chapter.
