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

BitBake is a program written in Python that interprets the metadata used by the OpenEmbedded
|
||
build system.
|
||
At some point, developers wonder what actually happens when you enter:
|
||
</p>
|
||
<pre class="literallayout">
|
||
$ bitbake core-image-sato
|
||
</pre>
|
||
<p>
|
||
</p>
|
||
<p>
|
||
This chapter provides an overview of what happens behind the scenes from BitBake's perspective.

|
||
BitBake strives to be a generic "task" executor that is capable of handling complex dependency relationships.
|
||
As such, it has no real knowledge of what the tasks being executed actually do.
|
||
BitBake just considers a list of tasks with dependencies and handles metadata
|
||
that consists of variables in a certain format that get passed to the tasks.
