Several varflags are useful for controlling how signatures are
calculated for variables.
For more information on this process, see the
"<link linkend='checksums'>Checksums (Signatures)</link>"
section.
<itemizedlist>
<listitem><para><emphasis>vardeps:</emphasis>
Specifies a space-separated list of additional
variables to add to a variable's dependencies
for the purposes of calculating its signature.
Adding variables to this list is useful, for example, when
a function refers to a variable in a manner that
does not allow BitBake to automatically determine
that the variable is referred to.
</para></listitem>
<listitem><para><emphasis>vardepvalue:</emphasis>
If set, instructs BitBake to ignore the actual
value of the variable and instead use the specified
value when calculating the variable's signature.
</para></listitem>
<listitem><para><emphasis>vardepsexclude:</emphasis>
Specifies a space-separated list of variables
that should be excluded from a variable's dependencies
for the purposes of calculating its signature.
</para></listitem>
<listitem><para><emphasis>vardepvalueexclude:</emphasis>
Specifies a pipe-separated list of strings to exclude
from the variable's value when calculating the
variable's signature.
