#
# Usage: qp2ap [options] <max-x> <max-y> <prg> <date>
#
# Filter that transforms a quasi-parallel profile (a .qp file) at stdin to  
# a PostScript file at stdout, showing an activity profile with one horizontal
# line for each task (thickness of the line shows if it's active or suspended).
#
# Options:
#  -o <file> ... write .ps file to <file>
#  -m        ... create mono PostScript file instead a color one.
#  -O        ... optimise i.e. try to minimise the size of the .ps file.
#  -s <n>    ... scaling factor of y axis (default: 1)
#  -w <n>    ... width of lines denoting running threads (default: 2) 
#  -v        ... be talkative. 
#  -h        ... print help message (this header).
