What are all the file extensions Alkaline indexes?

The default Alkaline behavior is to index all files with no extension and all html, htm, txt and shtml files. Alkaline can be instructed to index other file extensions with the ExtsAdd option. Alkaline is capable of indexing other document formats (for example Adobe PDF documents) by specifying an additional extension to index (ExtsAdd=pdf) and a plugin (Filter pdf=... ) converting the defined document format into text or HTML.

For more information on plugins, please refer to the Indexing Other Document Formats chapter in the Users Guide.
