44# In other words, the arguments should look like the command line you
45# want to run, with "|" used to list the alternatives for the parts
46# that you want to differ between the two runs.
47#
44# For example:
45#
46# % tracediff m5.opt --opt1 "--opt2|--opt3" --opt4
47# would compare these two runs:
48# m5.opt --opt1 --opt2 --opt4
49# m5.opt --opt1 --opt3 --opt4
50#
51# If you want to compare two different simulator binaries, put a '|'
