#
# Usage: gr2ps [options] <gr-file>
#
# Create an overall activity graph from a GrAnSim (or GUM) profile.
# Transform the log file of a GrAnSim run (a .gr file) into a quasi-parallel
# profile (a .qp file) using gr2qp and then into a PostScript file using qp2ps.
# The generated PostScript file shows essentially the number of running, 
# runnable and blocked tasks during the execution of the program.
#
# Options:
#  -o <file> ... write .ps file to <file>
#  -I <str>  ... queues to be displayed (in the given order) with the encoding
#                 'a' ... active (running)
#                 'r' ... runnable
#                 'b' ... blocked
#                 'f' ... fetching
#                 'm' ... migrating
#                 's' ... sparks
#                (e.g. -I "arb" shows active, runnable, blocked tasks)
#  -i <int>  ... info level from 1 to 7; number of queues to display
#  -m        ... create mono PostScript file instead a color one.
#  -O        ... optimise the produced .ps w.r.t. size
#		 NB: With this option info is lost. If there are several values
#		     with same x value only the first one is printed, all 
#		     others are dropped.
#  -s <str>  ... print <str> in the top right corner of the generated graph
#  -S        ... improved version of sorting events
#  -l <int>  ... length of slice in the .ps file; (default: 100)
#                small value => less memory consumption of .ps file & script
#  -d        ... Print date instead of average parallelism
#  -v        ... be talkative. 
#  -h        ... print help message (this header).
