8 * This traces Perl activity from all programs running on the system with
9 * Perl provider support.
11 * USAGE: pl_cpudist.d # hit Ctrl-C to end
13 * This script prints distribution plots of elapsed time for Perl subrotines.
14 * Use pl_cputime.d for summary reports.
17 * 1 Filename of the Perl program
18 * 2 Type of call (sub)
21 * Filename and subroutine names are printed if available.
