=item B<--program-name>=I<s>*

Program name that is being completed.

Can also be specified as the 1st command-line argument.

=item B<--strip>

Whether to strip source code using Perl::Stripper.

=item B<--subcommands-from-package-functions>

Form subcommands from functions under package's URL.

This is an alternative to the C<subcommand> option. Instead of specifying each
subcommand's name and URL, you can also specify that subcommand names are from
functions under the package URL in C<url>. So for example if C<url> is C</My/App/>,
hen all functions under C</My/App> are listed first. If the functions are:

 foo
 bar
 baz_qux

then the subcommands become:

 foo => /My/App/foo
 bar => /My/App/bar
 "baz-qux" => /My/App/baz_qux

=item B<--config-path>=I<s>, B<-c>

Set path to configuration file.

Can actually be specified multiple times to instruct application to read from
multiple configuration files (and merge them).


=item B<--config-profile>=I<s>, B<-P>

Set configuration profile to use.

A single configuration file can contain profiles, i.e. alternative sets of
values that can be selected. For example:

 [profile=dev]
 username=foo
 pass=beaver
 
 [profile=production]
 username=bar
 pass=honey

When you specify C<--config-profile=dev>, C<username> will be set to C<foo> and
C<password> to C<beaver>. When you specify C<--config-profile=production>,
C<username> will be set to C<bar> and C<password> to C<honey>.


=item B<--no-config>, B<-C>

Do not use any configuration file.

If you specify C<--no-config>, the application will not read any configuration
file.


=back

=head2 Environment options

=over

=item B<--no-env>

Do not read environment for default options.

If you specify C<--no-env>, the application wil not read any environment
variable.

=head2 Output options

=over

=item B<--format>=I<s>

Choose output format, e.g. json, text.

Default value:

 undef

Output can be displayed in multiple formats, and a suitable default format is
chosen depending on the application and/or whether output destination is
interactive terminal (i.e. whether output is piped). This option specifically
chooses an output format.


=item B<--json>

Set output format to json.

=item B<--naked-res>

When outputing as JSON, strip result envelope.

Default value:

 0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

 [200,"OK",[1,2,3],{"func.extra"=>4}]
