        !            33: produced by the

        !            35: subroutine.
        !            36: Under default modes,
        !            37: the symbol table in the

        !            40: default)
        !            41: is read and correlated with the

        !            43: .I (mon.out
        !            44: default).
        !            45: For each external symbol, the percentage
        !            46: of time spent executing between that symbol
        !            47: and the next
        !            48: is printed (in decreasing order),
        !            49: together with the number of times that routine was called
        !            50: and the number of milliseconds per call.
        !            51: If more than one profile file is specified,
        !            52: the output represents the sum of the profiles.
        !            53: .PP
        !            54: In order for the number of calls to a routine to be tallied,

        !            62: must have been given when the file containing the
        !            63: routine was compiled.
        !            64: This option also arranges for the
        !            65: profile file to be produced automatically.
        !            66: .PP

        !            82: This is really only useful

        !            86: all printing is suppressed
        !            87: and a graphic version of the profile
        !            88: is produced
        !            89: on the standard output for display by the

        !            91: filters.
        !            92: When plotting, the numbers
        !            93: .I low
        !            94: and 
        !            95: .I high,
        !            96: by default 0 and 100, may be given to cause a selected
        !            97: percentage of the profile to be plotted
        !            98: with accordingly higher resolution.

        !           100: .B \-z
        !           101: routines which have zero usage (as indicated by call counts
        !           102: and accumulated time) are nevertheless printed in the output.
