#
# This script will report the current status of portage.
#
# Usage:
# .conkyrc:     ${execi [time] /path/to/script/emerge-current.sh}
#
# Usage Example
#               ${execi 30 /home/youruser/scripts/emerge-current.sh}
#
# Known Bugs:
#  1) If there are two emerges running at once, when the first one finishes
#     running, the script will report the current status as "Completed".
#  2) If there is a emerge running and you run a search, the script will
#     report the current status as "Completed", until the running emerge
#     moves to the next package, or itself completes.
#  The reasons for this are twofold - one, it's a feature ;) and two, there
#  would be far too much parsing required to find out the current status of
#  every command which is run in parallel.
