=head1 NAME
sigtrap - Perl pragma to enable stack backtrace on unexpected signals
=head1 SYNOPSIS
use sigtrap;
use sigtrap qw(BUS SEGV PIPE SYS ABRT TRAP);
=head1 DESCRIPTION
The C<sigtrap> pragma initializes some default signal handlers that print
a stack dump of your Perl program, then sends itself a SIGABRT. This
provides a nice starting point if something horrible goes wrong.
By default, handlers are installed for the ABRT, BUS, EMT, FPE, ILL, PIPE,
QUIT, SEGV, SYS, TERM, and TRAP signals.
See L<perlmod/Pragmatic Modules>.
