# 
# This script uses a processed version (see boinc-stat.xsl) of the
# client_stat.xml data file to report the current activity in one BOINC slot.
#
# Usage: boinc-stat.sh SLOT
# Example:
# $ ./boinc-stat.sh 2
# 29.381600	<-- current wu progression
# 99.1		<-- current cpu usage
# 6 days, 19:16	<-- uptime
# shmoldu	<-- hostname
# $ 
#
# I've tested it under GNU/Linux only, problems may arise on other systems
# because of the calls to ps, and the usage of /proc, mainly.
