    #  There are three conditional tests:  select, bypass and test.
       They may appear as often as desired.  They must all pass for
       the fix to be applied.  "select" and "bypass" are egrep expressions
       that must each appear (or not appear) in the target file.
       "test" is an arbitrary test program expression that must yield
       true or false.  It is enclosed in parenthesis to avoid
       precedence problems.  The output looks like this:

       if ( test -n "`egrep 'find-expr' ${file}`" -a
