+# NAME
+#	extract_cfg 1
+# SUMMARY
+#	extract database parameter names from cfg_get_xxx() calls
+# SYNOPSIS
+#	\fBextract_cfg [-d|-s] [\fIfile...\fB]\fR
+# DESCRIPTION
+#	The \fBextract_cfg\fR command extracts the parameter names
+#	from cfg_get_{str,int,bool}() calls in dict_xxx.c files. The
+#	output is one parameter name per line, formatted as a C string
+#	followed by comma.
+#
+#	Options:
+# .IP \fB-d\fR
+#	Add the "domain" parameter to the output. This is used by
+#	the LDAP, memcache, and *SQL* tables.
+# .IP \fB-s\fR
+#	Add the legacy SQL query parameters: "select_field", "table",
+#	"where_field", and "additional_conditions".
+# LICENSE
+# .ad
