+ * @param[in]	database_path
+ * @parblock
+ * Path to existing database.
+ *
+ * A notmuch database is a Xapian database containing appropriate
+ * metadata.
  *
  * The database should have been created at some time in the past,
  * (not necessarily by this process), by calling
- * notmuch_database_create with 'path'. By default the database should be
- * opened for reading only. In order to write to the database you need to
- * pass the NOTMUCH_DATABASE_MODE_READ_WRITE mode.
+ * notmuch_database_create.
+ *
+ * If 'database_path' is NULL, use the location specified
+ *
+ * - in the environment variable NOTMUCH_DATABASE, if non-empty
+ *
+ * - in a configuration file, located as described under 'config_path'
+ *
+ * - by $XDG_DATA_HOME/notmuch/$PROFILE where XDG_DATA_HOME defaults
+ *   to "$HOME/.local/share" and PROFILE as as discussed in
+ *   'profile'
+ *
+ * If 'database_path' is non-NULL, but does not appear to be a Xapian
+ * database, check for a directory '.notmuch/xapian' below
+ * 'database_path' (this is the behavior of
+ * notmuch_database_open_verbose pre-0.32).

+ * @endparblock
+ * @param[in]	mode

+ * @parblock
+ * Path to config file.
+ *
+ * Config file is key-value, with mandatory sections. See
+ * <em>notmuch-config(5)</em> for more information. The key-value pair
+ * overrides the corresponding configuration data stored in the
+ * database (see <em>notmuch_database_get_config</em>)
  *
- * An existing notmuch database can be identified by the presence of a
- * directory named ".notmuch" below 'path'.
+ * If <em>config_path</em> is NULL use the path specified
+ *
+ * - in environment variable <em>NOTMUCH_CONFIG</em>, if non-empty
+ *
+ * - by  <em>XDG_CONFIG_HOME</em>/notmuch/ where
+ *   XDG_CONFIG_HOME defaults to "$HOME/.config".
+ *
+ * - by $HOME/.notmuch-config
+ *
+ * If <em>config_path</em> is "" (empty string) then do not
+ * open any configuration file.
+ * @endparblock
+ * @param[in] profile:
+ * @parblock
+ * Name of profile (configuration/database variant).
+ *
+ * If non-NULL, append to the directory / file path determined for
+ * <em>config_path</em> and <em>database_path</em>.
+ *
+ * If NULL then use
+ * - environment variable NOTMUCH_PROFILE if defined,
+ * - otherwise "default" for directories and "" (empty string) for paths.

+ * @param[out] database
+ * @parblock

  * The caller should call notmuch_database_destroy when finished with
  * this database.
