  Description     : Perl Memory Analysis Tool

The Devel::MAT ecosystem allows developers of perl programs to inspect and
analyse memory-related problems such as memory leaks, unexpected memory
consumption, or odd state. This is an "offline" analysis system, in the sense
that the analysis tools all run in a different process, possibly at a later
time, than the perl process that is being analysed.

The basic workflow consists of two main stages: first a heap dump file is
generated from the perl process being debugged, at or around the time that
the problem becomes apparent, and secondly this file is loaded by an analysis
tool in order to inspect the contents.

To generate the heap dump file that captures the contents of the heap, the
Devel::MAT::Dumper (libdevel-mat-dumper-perl) module is used.

Now that we have a .pmat file, we can load it and start to inspect the
contents. A lot of the smaller, simpler tools are built as plugins for the
main pmat command shell (contained in libdevel-mat-perl, together with
Devel::MAT), so we can start by loading the heap file there.

The package will be maintained under the umbrella of the Debian Perl Group.
