=head1 NAME
cpanfile-dump - Dump prerequisites from a cpanfile
=head1 SYNOPSIS
# Install typical required and recommended modules
cpan `cpanfile-dump`
# Skip configures phase
cpan `cpanfile-dump --no-configure`
# Also include develop phase and suggests type
cpan `cpanfile-dump --develop --suggests`
# Include a feature
cpan `cpanfile-dump --with-feature=sqlite`
=head1 DESCRIPTION
This script reads prereqs from a F<cpanfile> and dumps a raw list of
them to standard output. This is useful for piping these as input to
another program that doesn't support reading cpanfile directly,
i.e. C<cpan> or C<cpanp>.
By default, it prints configure, build, test and runtime requirements and
recommendations. Command line options can be used to modify the default
choices.
This script is distributed with L<Module::CPANfile> since version 1.0002.
=head1 OPTIONS
=over 4
=item --configure, --build, --test, --runtime, --develop
Specify the phase to include/exclude. Defaults to include all but
C<--develop> but you can exclude some phases by specifying the options with
C<--no-> prefix, like C<--no-configure>.
=item --requires, --recommends, --suggests, --conflicts
Specify the type to include/exclude. Defaults to include only C<--requires> and
C<--recommends> but you can exclude some types by specifying the options with
C<--no-> prefix, like C<--no-recommends>.
Specifying C<--conflicts> will turn off all other types (even if specified
on the command line).
=item --with-feature, --with-all-features, --without-feature
cpanfile-dump --with-feature=sqlite
cpanfile-dump --with-all-features --without-feature=yaml
Specify features to include in the dump. C<--with-feature> and C<--without-feature>
may be used more than once.
=back
=head1 NOTES
Because C<cpanm> supports reading cpanfile directly, instead of piping the output of this
program, you're recommended to use C<cpanm --installdeps .> to install modules from cpanfile.
