Store flags in a file

To fully customize your needs, you may need to add a few flags for perprof. The best way to do this is to create a file with a flag in each line and calling perprof with that file as argument, with a @ preceding the file name:

$ perprof @filename [more flags] FILE1 FILE2 [FILE3 ...]

For a example you can look at test/pdf.args. To use it, enter

$ perprof @test/pdf.args -f -o tmp test/*.long

Please note that the arguments in the file and in the command line are treated equally, so you can’t add conflicting options.
