+ MIT supplies an authentication mechanism that relies upon DES, this is
+ called XDM-AUTHORIZATION-1.
+
+ Source code for this authentication mechanism may not be exported from
+ the United States, however, there are compatible replacements for this
+ mechanism available elsewhere.  Also, while this scheme is not used for
+ general purpose encryption,  some countries restrict the use of strong
+ cryptography.
+
+ If you have aquired a copy of "Wraphelp.c" and it currently resides in
+ the same location as the XFree86 upgrade patches or in the ports "files"
+ subdirectory,  it will be copied into the right place in the X11 source
+ distribution and support for this feature will be enabled if you answer
+ YES to the following question.
+
+ If you do not have a copy of this file, even if you answer YES to this
+ question, support will not be enabled.  If you wish to change this later,
+ the option controling this is contined the file xc/config/cf/xf86site.def.
