+ <p>If you maintain several buildroot trees, it might be better to have
+ a shared download location. This can be accessed by creating a symbolic link

+ln -s &lt;shared download location&gt; dl

+ <p>Another way of accessing a shared download location is to

+ If this is set, then the value of DL_DIR in the project is
+ overridden. The following line should be added to
+ <code>&quot;~/.bashrc&quot;</code>. <p>
