+/* NAME
+/* mail_conf_bool 3
+/* SUMMARY
+/* boolean-valued configuration parameter support
+/* SYNOPSIS
+/* #include <mail_conf.h>
+/*
+/* int get_mail_conf_bool(name, defval)
+/* const char *name;
+/* int defval;
+/*
+/* int get_mail_conf_bool_fn(name, defval)
+/* const char *name;
+/* int (*defval)();
+/*
+/* void set_mail_conf_bool(name, value)
+/* const char *name;
+/* int value;
+/*
+/* void get_mail_conf_bool_table(table)

+/*
+/* void get_mail_conf_bool_fn_table(table)
+/* const CONFIG_BOOL_TABLE *table;
+/* DESCRIPTION
+/* This module implements configuration parameter support for
+/* boolean values. The internal representation is zero (false)
+/* and non-zero (true). The external representation is "no"
+/* (false) and "yes" (true). The conversion from external
+/* representation is case insensitive.
+/*
+/* get_mail_conf_bool() looks up the named entry in the global
+/* configuration dictionary. The specified default value is
+/* returned when no value was found.
+/*
+/* get_mail_conf_bool_fn() is similar but specifies a function that
+/* provides the default value. The function is called only
+/* when the default value is needed.
+/*
+/* set_mail_conf_bool() updates the named entry in the global
+/* configuration dictionary. This has no effect on values that
+/* have been looked up earlier via the get_mail_conf_XXX() routines.
+/*
+/* get_mail_conf_bool_table() and get_mail_conf_int_fn_table() initialize
+/* lists of variables, as directed by their table arguments. A table
+/* must be terminated by a null entry.
+/* DIAGNOSTICS
+/* Fatal errors: malformed boolean value.
+/* SEE ALSO
