 -v              verbose output
 -V              print version
 -1              no binary chopping...go one-by-one
 -d diff_script  script file takes 2 arguments and
                 exits 0 if no difference.
                 def: "diff -b $1 $2 > /dev/null"
 -o outfile      output file to compare.
                 def: stdout
 -i infile       stdin file for runs.
                 e.g. "./a.out < infile"
 -C cmd_line     command line arguments for runs
 -c load_cmd     command to link objects.
                 def: "cc -o "
 -llibs          added libraries for linking objects
 -Llibdirs       additional directories to search
                 for libraries
 -O okobjects    added objects to link with
 -f objlistfile  list of objects to link together
