Link to libcipher in the usual way. `bdes' depended on a nonexistent
library. This only worked because of the undocmented feature of make(1)
that targets named foo.a are always up to date.

Fixed some style bugs.

man(7) -> mdoc(7).

Add missing $FreeBSD$ to files that are NOT still on vendor a branch.

$Id$ -> $FreeBSD$

Typo in comment.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Bring in my changes for removing the pestilent obj links (unless you
really want them) from /usr/src. This is the final version of the
patches, incorporating the feedback I've received from -current.

Correct some manual page cross reference errors. E.g. su is a section
one man page, not section eight. This is the first round of such changes
and only fixes man pages in manual section one.

Pick correct library dir whenever obj exists or not

Remove trailing whitespace.

Make the "distribute" target build the "des" distribution. Make des'ed
init and ed, by pointing to real sources.

!Just! fixing makefile, no code changes Geoff

Add libcipher.a: libcrypt exports only crypt() but not des_setkey()
which is in libcipher.a

Remove static in front of declarations for des_setkey and des_cipher
so that linking against -lcrypt (-ldescrypt) will give us the good
versions instead of the stubs in libc. (These changes need to be
made to the non-US version of libdescrypt too!)

Allow building and support for bdes program.
A bit more work still needs to be done on secure telnet.

Moved from usr.bin/bdes for export-control.
