+\subsubsection{Ignoring directories during database initialization}
+
+You may have directories on your \dap{} whose contents should not be added
+to the database. Placing a file named \fname{database.ignore} in a directory
+will exclude the files in that directory and all its subdirectories from
+scanning their tags and adding them to the database. This will speed up the
+database initialization.
+
+If a subdirectory of an 'ignored' directory should still be scanned, place a
+file named \fname{database.unignore} in it. The files in that directory and
+its subdirectories will be scanned and added to the database.
