9.7 Diffsummary

The `diffsummary` command writes a short report to the console giving the number of difference operations that have taken place and how many of the pairs of files compared were identical. Counting starts at the most recent execution of a `diffzero` command, or if there has been none, when FunnelWeb started up.

    Syntax  : diffsummary = "diffsummary"
    Examples: diffsummary

The `diffsummary` command was added so as to allow regression testing scripts to display a summary of the results of the test. If the summary indicates that no pair of files differed, then there is no need to look in the `diff` log file.
