# Blueprint to build smartmontools-5.39.1.
#
# The smartmontools package contains utilities to monitor the health
# of hard drives equiped with Self-Monitoring, Analysis and Reporting
# Technology (S.M.A.R.T.).  Many modern drives have this capability.

# staging directory paths.  Prefixes to directories may be overridden
# by setting shell variables SRC, BUILD and STAGING.  For example,
# doing "export SRC=/root/foo" before calling this script will override
# the default /usr/src and set SRC_DIR to /root/foo/$PKG_NAME instead.
