# Usage: AVG [options] <gr-file>
#
# A quich hack to get avg runtimes of different spark sites. Similar to SPLIT.
#
# Options:
#  -s <list> ... a perl list of spark names; the given <gr-file> is scanned 
#                for each given name in turn and granularity graphs are 
#                generated for each of these sparks  
#  -O        ... use gr2RTS and RTS2gran instead of gran-extr;
#                this generates fewer output files (only granularity graphs)
#                but should be faster and far less memory consuming
#  -h        ... help; print this text.
#  -v        ... verbose mode.
