+=head1 PACKAGE VARIABLES
+
+=over 4
+
+=item $MAP_SECTION_SPACE_TO_NESTED_KEY (boolean)
+
+This variable controls whether spaces in INI section headings will be expanded into nested hash keys.
+e.g. it controls whether [Full Power] maps to $config->{'Full Power'} or $config->{'Full'}->{'Power'}
+
+By default it is set to 1 (i.e. true). 
+
+Set it to 0 to preserve literal spaces in section headings:
+
+    use Config::Any;
+    use Config::Any::INI;
+    $Config::Any::INI::MAP_SECTION_SPACE_TO_NESTED_KEY = 0;
