=head1 NAME

IPC::Run3::ProfPP - Generate reports from IPC::Run3 profiling data

=head1 SYNOPSIS

=head1 DESCRIPTION

Used by IPC::Run3 and/or run3profpp to print out profiling reports for
human readers.  Use other classes for extracting data in other ways.

The output methods are plain text, override these (see the source for
now) to provide other formats.

This class generates reports on each run3_exit() and app_exit() call.
