.SH DESCRIPTION
.IX Header "DESCRIPTION"
This script reads prereqs from a \fIcpanfile\fR and dumps a raw list of
them to standard output.  This is useful for piping these as input to
another program that doesn\*(Aqt support reading cpanfile directly,
i.e. \f(CW\*(C`cpan\*(C'\fR or \f(CW\*(C`cpanp\*(C'\fR.
.PP
By default, it prints configure, build, test and runtime requirements and
recommendations.  Command line options can be used to modify the default
choices.
.PP
This script is distributed with Module::CPANfile since version 1.0002.
.SH OPTIONS
.IX Header "OPTIONS"
.IP "\-\-configure, \-\-build, \-\-test, \-\-runtime, \-\-develop" 4
.IX Item "--configure, --build, --test, --runtime, --develop"
Specify the phase to include/exclude. Defaults to include all but
\&\f(CW\*(C`\-\-develop\*(C'\fR but you can exclude some phases by specifying the options with
\&\f(CW\*(C`\-\-no\-\*(C'\fR prefix, like \f(CW\*(C`\-\-no\-configure\*(C'\fR.
.IP "\-\-requires, \-\-recommends, \-\-suggests, \-\-conflicts" 4
.IX Item "--requires, --recommends, --suggests, --conflicts"
Specify the type to include/exclude. Defaults to include only \f(CW\*(C`\-\-requires\*(C'\fR and
\&\f(CW\*(C`\-\-recommends\*(C'\fR but you can exclude some types by specifying the options with
\&\f(CW\*(C`\-\-no\-\*(C'\fR prefix, like \f(CW\*(C`\-\-no\-recommends\*(C'\fR.
.Sp
Specifying \f(CW\*(C`\-\-conflicts\*(C'\fR will turn off all other types (even if specified
on the command line).
.IP "\-\-with\-feature, \-\-with\-all\-features, \-\-without\-feature" 4
.IX Item "--with-feature, --with-all-features, --without-feature"
.Vb 2
\&    cpanfile\-dump \-\-with\-feature=sqlite
\&    cpanfile\-dump \-\-with\-all\-features \-\-without\-feature=yaml
.Ve
.Sp
Specify features to include in the dump.  \f(CW\*(C`\-\-with\-feature\*(C'\fR and \f(CW\*(C`\-\-without\-feature\*(C'\fR
may be used more than once.
.SH NOTES
.IX Header "NOTES"
Because \f(CW\*(C`cpanm\*(C'\fR supports reading cpanfile directly, instead of piping the output of this
program, you\*(Aqre recommended to use \f(CW\*(C`cpanm \-\-installdeps .\*(C'\fR to install modules from cpanfile.
