<para>
A list of recipe dependencies that should not be used to
determine signatures of tasks from one recipe when they
depend on tasks from another recipe.
For example:
<literallayout class='monospaced'>
SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS += "intone->mplayer2"
</literallayout>
In this example, <filename>intone</filename> depends on
<filename>mplayer2</filename>.
</para>
<para>
Use of this variable is one mechanism to remove dependencies
that affect task signatures and thus force rebuilds when a
recipe changes.
<caution>
If you add an inappropriate dependency for a recipe
relationship, the build might break when the interface
of the second recipe changes after the first recipe has
been built.
