41 -n,--progname=NAME Name of the program file to profile
42 -p,--png=FILE Generate PNG graphic and store it in FILE
43 -d,--data=FILE Generate binary data file and store it in FILE
44 -u,--unbuffered Don't buffer output
45 -b,--buffer=SIZE Collect SIZE entries before writing them out
46 --no-timer Don't collect additional information though timer
48 -?,--help Print this help and exit
49 --usage Give a short usage message
50 -V,--version Print version information and exit
52 The following options only apply when generating graphical output:
53 -t,--time-based Make graph linear in time
54 -T,--total Also draw graph of total memory use
55 --title=STRING Use STRING as title of the graph
56 -x,--x-size=SIZE Make graphic SIZE pixels wide
57 -y,--y-size=SIZE Make graphic SIZE pixels high
59 Mandatory arguments to long options are also mandatory for any corresponding
60 short options.
