#
# This script will report the progress of the last emerge command run. It
# reports the TOTAL percentage complete - not the percentage of the current
# package. For example, if there are 110 packages currently being emerged, and
# it is on the 55th package, it will report 50.
#
# Usage:
# .conkyrc: ${execibar [time] /path/to/script/emerge-progress.sh}
#
# Usage Example
# ${execibar 30 /home/youruser/scripts/emerge-progress.sh}
