#chroot environments. Variable assignments in later
#includes override earlier ones.

#file.

# are NOT intended to be used for user customization of builds.
# In addition, the names of variables to be included in the
# scoreboard file must begin with "CNAS_".

# config/bootstrap
# config/chroot
# config/binary
# config/source
