=head1 NAME
Data::Peek - A collection of low-level debug functions
=head1 Description
Modified and extended wrapper functions to make debugging more
pleasurable.
DDumper () is a wrapper around Data::Dumper with always sorted keys.
The output is however reflowed and not parsable anymore (in most
cases) as the quotation around the keys is removed.
DDump () is a wrapper around perl's core function sv_dump (), which
should enable you to use the output instead of the default behavior
that only prints to STDERR.
DPeek () is a wrapper around internals Perl_sv_peek
DDump_IO () is a wrapper around perl's core function do_sv_dump (),
which acts like sv_dump (), but to a PerlIO stream.
=head1 PREREQUISITES
Perl 5.8.0 and up.
Some versions of perl on some operating system(s) might not have
exported the internals (yet). This module won't build then.
If you run a perl that did not export Perl_sv_peek (), DPeek will
not be available. If you happen to encounter that problem, most
likely on Windows or AIX, C<export NO_SV_PEEK=1> will make the
build and test pass (I hope)
=head1 INSTALLATION
$ perl Makefile.PL
$ make
$ make test
$ make install
