+ Regular expression that must match the directory name for
+ the directory to be considered for the output of the query.
+ See regex(7) for details.
+
+ Depending on whether --print-base-dir is given, the absolute
+ directory name or only the part of the directory name below
+ the base directory is matched against \"regex\".
+
+ If this option is not given (the default) all directories
+ are taken into account.
+
+ If \"regex\" starts with '!', directories are matched against
+ the remaining part of \"regex\" and the sense of matching is
+ reversed.

+"use a customized header for listings/summaries"
+string typestr="string"
+optional
+details="
+ This option can be used to print any string instead of the
+ default header line (which depends on the selected mode).
+
+ In user_list mode the header is a format string which allows
+ to include the uid and the user name in the header. See the
+ --format option for more details.
+
+ It is possible to set this to the empty string to suppress
+ the header completely. This is mostly useful to feed the
+ output to scripts.

+default=""
+details="
+ This option can be used to print any string at the end of
+ the query output.
+
+ In user_list mode the trailer is a format string with the
+ same semantics like the header string.
