Can I get rid of build output so I can start over?

<answer>
<para>
Yes - you can easily do this.
When you use BitBake to build an image, all the build output goes into the
directory created when you source the <filename>oe-init-build-env</filename>
setup file.
By default, this <ulink url='&YOCTO_DOCS_DEV_URL;#yocto-project-build-directory'>Yocto
Project Build Directory</ulink> is named <filename>build</filename> but can be named
anything you want.
</para>
<para>
Within the Yocto Project Build Directory is the <filename>tmp</filename>
directory.
To remove all the build output yet preserve any source code or downloaded files
from previous builds, simply remove the <filename>tmp</filename> directory.
