-Generate HTML gallery pages for a picture directory organized along::
+CGI gallery server for a picture directory organized along::
pics
|-- some_directory
Note that you can store a caption for ``<PICTURE>`` as plain text in
``<PICTURE>.txt``.
-The resulting gallery pages will be::
-
- pics
- |-- some_directory
- | |-- a_picture.jpg
- | |-- another_picture.jpg
- | |-- ...
- | |-- <INDEX> -> <GALLERY-1>
- | |-- <GALLERY-1>
- | |-- <GALLERY-2>
- | |-- <GALLERY-...>
- | |-- <THUMBDIR>
- | | |-- a_picture.png
- | | |-- another_picture.png
- | | |-- ...
- | |-- <PAGEDIR>
- | | |-- a_picture.html
- | | |-- another_picture.html
- | | |-- ...
- |-- ...

-So you'll probably want to symlink index.html to <GALLERY-1>.
