Because of the United States export restriction on DES implementations,
we are distributing this code separately from the rest of the C library.
There is an extra distribution tar file just for crypt; it is called
`glibc-VERSION-crypt.tar.Z', e.g. `glibc-1.04-crypt.tar.Z'. You can just
unpack the crypt distribution along with the rest of the C library and
