+# 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
