=head1 NAME
stations_visited | StationVisited
routeChange | RouteChange
-=head2 column_accessor_map
+=head2 col_accessor_map
Same as moniker_map, but for column accessor names. If a coderef is
passed, the code is called with arguments of
classes. A good example would be
L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
+=head2 result_component_map
+
+A hashref of moniker keys and component values. Unlike C<components>, which loads the
+given components into every table class, this option allows you to load certain
+components for specified tables. For example:
+
+ result_component_map => {
+ StationVisited => '+YourApp::Schema::Component::StationVisited',
+ RouteChange => [
+ '+YourApp::Schema::Component::RouteChange',
+ 'InflateColumn::DateTime',
+ ],
+ }
+
+You may use this in conjunction with C<components>.
+
=head2 use_namespaces
This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
col_collision_map => { '(foo).*(bar)' => 'column_%s_%s' }
+=head2 rel_collision_map
+
+Works just like L</col_collision_map>, but for relationship names/accessors
+rather than column names/accessors.
+
+The default is to just append C<_rel> to the relationship name, see
+L</RELATIONSHIP NAME COLLISIONS>.

+=head1 RELATIONSHIP NAME COLLISIONS
+
+In very rare cases, you may get a collision between a generated relationship
+name and a method in your Result class, for example if you have a foreign key
+called C<belongs_to>.
+
+This is a problem because relationship names are also relationship accessor
+methods in L<DBIx::Class>.
+
+The default behavior is to append C<_rel> to the relationship name and print
+out a warning that refers to this text.
+
+You can also control the renaming with the L</rel_collision_map> option.
