=head1 Description

C<Apache2::Command> provides the Perl API for accessing Apache module
command information






=head1 API

C<Apache2::Command> provides the following functions and/or methods:






=head2 C<args_how>

What the command expects as arguments:

  $how = $cmd->args_how();

=over 4

=item obj: C<$cmd>
( C<L<Apache2::Command object|docs::2.0::api::Apache2::Command>> )

=item ret: C<$how> ( C<L<Apache2::Const :cmd_how
constant|docs::2.0::api::Apache2::Const/C__cmd_how_>> )

The flag value representing the type of this command
(i.e. C<Apache2::Const::ITERATE>, C<Apache2::Const::TAKE2>).

=item since: 2.0.00

=head2 C<errmsg>

Get I<usage> message for that command, in case of syntax errors:

  $error = $cmd->errmsg();

=over 4

=item obj: C<$cmd>
( C<L<Apache2::Command object|docs::2.0::api::Apache2::Command>> )

=item ret: C<$error> ( string )

The error message

=item since: 2.0.00

=back







=head2 C<name>

Get the name of this command:

  $name = $cmd->name();

=over 4

=item obj: C<$cmd>
( C<L<Apache2::Command object|docs::2.0::api::Apache2::Command>> )

=item ret: C<$name> ( string )

The command name

=item since: 2.0.00

=back






=head2 C<next>

Get the next command in the chain of commands for this module:

  $next = $cmd->next();

=over 4

=item obj: C<$cmd>
( C<L<Apache2::Command object|docs::2.0::api::Apache2::Command>> )

=item ret: C<$next>
( C<L<Apache2::Command object|docs::2.0::api::Apache2::Command>> )

Returns the next command in the chain for this module, C<undef> for
the last command.

=item since: 2.0.00

=head2 C<req_override>

What overrides need to be allowed to enable this command:

  $override = $cmd->req_override

=over 4

=item obj: C<$cmd>
( C<L<Apache2::Command object|docs::2.0::api::Apache2::Command>> )

=item ret: C<$override> ( C<L<Apache2::Const :override
constant|docs::2.0::api::Apache2::Const/C__override_>> )

The bit mask representing the overrides this command is allowed in
(i.e C<Apache2::Const::OR_ALL>/C<Apache2::Const::ACCESS_CONF>).

=item since: 2.0.00

=back

For example:

  use Apache2::Const -compile => qw(:override);
  $cmd->req_override() & Apache2::Const::OR_AUTHCFG;
  $cmd->req_override() & Apache2::Const::OR_LIMIT;
