DESCRIPTION

This module replace $SIG{__DIE__} to function, who added to exception stacktrace.

If exeption is string, then stacktrace added to message. And if exeption is hash ({}), or object on base hash (bless {}, "..."), then added to it key STACKTRACE with stacktrace.

Where use propagation, stacktrace do'nt added.
