+ <para>
+ You might find it helpful during development to modify the
+ temporary source code used by recipes to build packages.
+ For example, suppose you are developing a patch and you need to
+ experiment a bit to figure out your solution.
+ After you have initially built the package, you can iteratively
+ tweak the source code, which is located in the
+ <ulink url='&YOCTO_DOCS_REF_URL;#build-directory'>Build Directory</ulink>,
+ and then you can force a re-compile and quickly test your altered
+ code.
+ Once you settle on a solution, you can then preserve your changes
+ in the form of patches.
