README for crypt

1. This source comes from the GNU crypt distribution. 

2. It generally illegal to ship the encrypt() function outside the US.  
Therefore, that code has been #ifdef'd out in Be's version.

3. It is legal to ship to crypt() though, since it is only used for
authentication, and not data encryption.

4. The source to this cannot be shipped to anyone outside the US.
Be has therefore not provided the source here.

If you are able to legally obtain a copy of the source, you can
uncomment the relevant lines in the makefile and recompile it.
Be uses only four source files from the crypt distribution.  Simply
copy those files to this directory, and uncomment the relevant lines
in the libroot Makefile.  The filenames and versions are:

 * @(#)crypt.c	2.20 05/18/93
 * @(#)crypt_util.c	2.43 5/18/93
 * @(#)patchlevel.h	1.12 05/18/93
 * @(#)ufc-crypt.h	1.19 7/29/93

5. The only modification to these files was to #ifdef out the encrypt()
function.
