# 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 ':'.

lm_sensors: lm_sensors (Linux sensors drivers and hardware monitoring tools)
lm_sensors:
lm_sensors: lm_sensors provides essential drivers for monitoring the
lm_sensors: temperatures, voltages, and fans of Linux systems with hardware
lm_sensors: monitoring devices. It contains Linux 2.4 drivers for sensor chips
lm_sensors: and I2C and SMBus masters, text-based tools for sensor reporting,
lm_sensors: and a library for sensors access called "libsensors". It also
lm_sensors: contains tools for sensor hardware identification and I2C bus probing.
