=head1 NAME

ACME::Error - Never have boring errors again!

=head1 SYNOPSIS

  use ACME::Error SHOUT;
  
  warn "Warning"; # WARNING!

=head1 DESCRIPTION

C<ACME::Error> is a front end to Perl error styles.  C<$SIG{__WARN__}> and C<$SIG{__DIE__}>
are intercepted.  Backends are pluggable.  Choose a backend by specifying it when you
C<use ACME::Error SomeStyle>;

=head2 Writing Backends

Writing backends is easy.  See L<ACME::Error::SHOUT> for a simple example.  Basically your
backend needs to be in the C<ACME::Error> namespace and defines just two subroutines, C<warn_handler>
and C<die_handler>.  The arguments passed to your subroutine are the same as those passed to the signal
handlers, see L<perlvar> for more info on that.  You are expected to C<return> what you want to be
C<warn>ed or C<die>d.
