6 # This program will inspect a log file with relay information and tell you
7 # whether calls and returns match. If not, this suggests that the parameter
8 # list might be incorrect. (It could be something else also.)
10 # This program now accepts a second command line parameter, which will enable
11 # a "full" listing format; otherwise a trimmed down simplified listing is
12 # generated. It does not matter what the second command line parameter is;
13 # anything will enable the full listing.
