# depend= is metadata only - scraps-build does not stage a recipe's declared
# dependencies onto the build host before running build(). Every package in
# the skarnet chain needs skalibs' headers, libraries and sysdeps directory
# to exist somewhere real at configure time, so each one stages it out of
# the repo itself.
