+{\bf NB:} this function is not in the base wxConfigBase class but is only
+implemented in wxFileConfig. Moreover, this function is Unix-specific and
+doesn't do anything on other platforms.
+
+SetUmask() allows to set the mode to be used for the config file creation.
+For example, to create a config file which is not readable by other users
+(useful if it stores some sensitive information, such as passwords), you
+should do {\tt SetUmask(0077)}.
