0.4.0
	o toc() and toc_by_attribute() no more print a title
	  for the table of contents. It is up to the page
	  editor to write a title.

	o added attribute support. the admin (root) can define
	  any number of attributes with one or more pre-defined
	  values, which can later be used by page editors to
	  classify pages.

	o added custom variable support. the admin (root) can
	  define any number of variables which can be used
	  by page editors using the dollar notation ($variable).

	o the L<> and P<> handlers are now able to recognize
	  CGI variables (e.g.: P<state:toc_by_attribute?topic=main>.

	o new public available handler: toc_by_attribute, which
	  lists all pages which are classified by the specified
	  attribute (CGI notation, see above)

	o page properties such as options or attibutes will be
	  inherited by new pages during creation (first state=edit
	  call on non-existent page).

	o bug fix: if a page referenced by P<> were not existent,
	  the page creation link were wrong, it pointed to
	  the current page, not the page to be created.

	o moved the image index code to separate sub to make it
	  possible to display the image index on the edit page
	  too.

	o renamed imageindex to fileindex, which is more appropriate.

	o added fileindex to edit() page

	o bug fix: </tr> missing on pageindex() and fileindex()
	  after each list item.

	o added diff support on the info page, including color
	  highlighting.

	o removed hardcoded path to 'rcs', added configure variable
	  for this.

	o added X<> support to build a user maintained search
	  index.

	o enhanced search engine, it can now search for indixed pages
	  and for attributes (classified pages).

	o added protection from setup() from being executed via CGI
	  after the setup has already been done.
	  
	o added tumbnail preview support for images using ImageMagick
	  (convert), if present. added configure.in check for this.
	  added config variables 'image_magick' (path) and tumbsize
	  (integer).

	o changed versioning scheme:
          0.4.0
          | | |
          | | +-- patchlevel (increment by bugfix)
          | +---- minor version (enhancements, feature additions)
          +------ major version (core changes, releases)

	o added support for http: links to local files on the same
	  webserver. Such links must begin with http:// and the
	  uri itself must start with . or /, e.g.: L<printer.html|http://./printer.html>
	  generates: <a href="./printer.html">printer.html</a>.

	o bugfix: under mod_perl data were not properly written(flushed)
	  to disk when something has changed.

	o bugfix: walk_ordinary does no more print redundant <p>..</p>
	  tags for include-pages only (such as AutoLoad).

	o bugfix: multiline paragraphs will now be treated as a single
	  paragraphs and no more multiple paragraphs (one per line).
	  This is the same behavior of standard POD parsers, i.e. like
	  'perldoc'.

	o bugfix: UPDATE support in configure.in and Makefile.in added,
	  configure now checks if a previous version of PodWiki is
	  already installed in the $prefix directory and preserves
	  the existing data files (.htaccess, podwiki.conf and the like).
