+/*	const CONFIG_RAW_TABLE *table;
+/* DESCRIPTION
+/*	This module implements support for string-valued global
+/*	configuration parameters that are loaded without $name expansion.
+/*
+/*	get_mail_conf_raw() looks up the named entry in the global
+/*	configuration dictionary. The default value is returned when
+/*	no value was found. String results should be passed to myfree()
+/*	when no longer needed.  \fImin\fR is zero or specifies a lower
+/*	bound on the string length; \fImax\fR is zero or specifies an
+/*	upper limit on the string length.
+/*
+/*	get_mail_conf_raw_fn() is similar but specifies a function that
+/*	provides the default value. The function is called only when
+/*	the default value is used.
+/*
+/*	get_mail_conf_raw_table() and get_mail_conf_raw_fn_table() read
+/*	lists of variables, as directed by their table arguments. A table
+/*	must be terminated by a null entry.
+/* DIAGNOSTICS
+/*	Fatal errors: bad string length.
+/* SEE ALSO
+/*	config(3) generic config parameter support
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
