+=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.

+=head1 NAME
+
+mymeta-cpanfile - Dump cpanfile out of (MY)META files
+
+=head1 SYNOPSIS
+
+  perl Makefile.PL # or Build.PL
+  mymeta-cpanfile
+
+  # Skip configures phase and suggests type
+  mymeta-cpanfile --no-configure --no-suggests
+
+  # Include empty blcok for phases without prereqs
+  mymeta-cpanfile --include-empty
+
+=head1 DESCRIPTION
+
+This script reads prereqs metadata from MYMETA files in the current
+directory and prints C<cpanfile> that represents the prereqs. Useful
+when you want to migrate to using L<cpanfile> from existing
+C<Makefile.PL> or C<Build.PL> with dependency specification.
+
+This script is distributed with L<Module::CPANfile> since version 0.9021.

+but you can exclude some types by specifying the options with C<--no->
+prefix, like C<--no-conflicts>.
+
+=item --include-empty
+
+By default, phases without any prereqs are not dumped, By giving this
+option, cpanfile will have an empty block such as:
+
+  on test => sub {
+
+  };
+
+Defaults to false.
