suikawiki-config.ph - SuikaWiki: Configuration for SuikaWiki HTTP CGI Driver

=head1 DESCRIPTION

This is a configuration file for SuikaWiki Driver for HTTP CGI Script
(SWHCS).  Basic options such as WikiDB directory mapping and
special purpose WikiPage names can be customized with this file.

More complex customizing, e.g. modifying navigation bar or
adding new mode, is also possible by config.ph (generated from
config.wp2) and WikiPlugin modules.  For more information,
see <http://suika.fam.cx/~wakaba/-temp/wiki/wiki?SuikaWiki>.

This file is part of SuikaWiki.
