This is the path of the C<E<lt>LocationE<gt>> block. Some directives need this,

+
+Apache limits the applicable directives in certain situations with
+C<AllowOverride>. With Apache 2.2 comes the possibility to enable or
+disable single options, for example
+
+ AllowOverride AuthConfig Options=ExecCGI,Indexes
+
+Internally, this directive is parsed into 2 bit fields that are represented
+by the C<$override> and C<$override_opts> parameters to C<add_config>.
+The above example is parsed into an C<$override> with 2 bits set, one for
+C<AuthConfig> the other for C<Options> and an C<$override_opts> with
+2 bits set for ExecCGI and Indexes.
+
+When applying other directives, for example C<AuthType> or C<Options> the
+appropriate bits in C<$override> must be set. For the C<Options> directive
+additionally C<$override_opts> bits must be set.
+
+The C<$override> and C<$override_opts> parameters to C<add_config> are
+valid while applying C<$lines>.
+
+C<$override_opts> is new in Apache 2.2. The mod_perl implementation for
+Apache 2.0 lets you pass the parameter but ignores it.
+
+Default for C<$override_opts> is:
+C<L<Apache2::Const::OPT_UNSET|docs::2.0::api::Apache2::Const/C_Apache2__Const__OPT_UNSET_>> |
+C<L<Apache2::Const::OPT_ALL|docs::2.0::api::Apache2::Const/C_Apache2__Const__OPT_ALL_>> |

+C<L<Apache2::Const::OPT_MULTI|docs::2.0::api::Apache2::Const/C_Apache2__Const__OPT_MULTI_>>
