# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|' on
# the right side marks the last column you can put a character in.  You must make
# exactly 11 lines for the formatting to be correct.  It's also customary to
# leave one space after the ':'.

hddtemp: hddtemp.SlackBuild by Rudson R. Alves
hddtemp:
hddtemp: hddtemp is a small utility that gives you the temperature of your
hddtemp: hard drive by reading S.M.A.R.T. informations (for drives that
hddtemp: support this feature).
hddtemp: Note: only recent hard drives have a temperature sensor.
hddtemp:
hddtemp: The temperature information seems to be vendor specific (i.e. not
hddtemp: standardized). So hddtemp comes with a file (hddtemp.db) that contains
hddtemp: informations about drives that were reported to work with hddtemp.
