org: Selecting files

 
 13.1.3 Selecting files
 ----------------------
 
 By default, all files with extension ‘.org’ in the base directory are
 considered part of the project.  This can be modified by setting the
 properties
 ‘:base-extension’  Extension (without the dot!)  of source files.  This
                    actually is a regular expression.  Set this to the
                    symbol ‘any’ if you want to get all files in
                    ‘:base-directory’, even without extension.
                    
 ‘:exclude’         Regular expression to match file names that should
                    not be published, even though they have been
                    selected on the basis of their extension.
                    
 ‘:include’         List of files to be included regardless of
                    ‘:base-extension’ and ‘:exclude’.
                    
 ‘:recursive’       non-‘nil’ means, check base-directory recursively
                    for files to publish.
