Hi,

is there a description of BUILD_DEFS? I wonder which variables to add to
BUILD_DEFS.

So far, I think BUILD_DEFS should contain variables which directly
influence how a package is built. Variables whose only purpose is to
give the user a knob to add useful packages as a prerequisite and do not
alter the content of a package should not be added to BUILD_DEFS. Is this
the correct approach?

The fact, that BUILD_DEFS will be displayed before the 'extract' stage
tempts me to add the latter kind of variables to inform the user of
their existence.

ciao
