# Usage: gr2gran [options] <sim-file>
#
# Create granularity graphs for the GrAnSim profile <sim-file>. This creates
# a bucket statistics and a cumulative runtimes graph.
# This script is derived from the much more complex gran-extr script, which
# also produces such graphs and much more information, too.
#
# Options:
#  -t <file>   ... use <file> as template file (<,> global <.> local template)
#  -p <file>   ... use <file> as gnuplot .gp file (default: gran.gp)
#  -x <x-size> ... of gnuplot graph
#  -y <y-size> ... of gnuplot graph
#  -n <n>      ... use <n> as number of PEs in title 
#  -o <file>   ... keep the intermediate <file> (sorted list of all runtimes)
#  -h          ... help; print this text.
#  -v          ... verbose mode.
