-<P>This command does not use the syntax conventions of the AFS command
-suites. Provide the command name and all option names in full.
-<P><STRONG>Description</STRONG>
-<P>The <B>upserver</B> command initializes the server portion of the
-Update Server (the <B>upserver</B> process). In the conventional
-configuration, its binary file is located in the <B>/usr/afs/bin</B>
-directory on a file server machine.
-<P>The <B>upserver</B> command is not normally issued at the command shell
-prompt but rather placed into a file server machine's
-<B>/usr/afs/local/BosConfig</B> file with the <B>bos create</B>
-command. If it is ever issued at the command shell prompt, the issuer
-must be logged onto a database server machine as the local superuser
-<B>root</B>.
-<P>The <B>upserver</B> command specifies which of the directories on the
-local disk are eligible for distribution in response to requests from the
-client portion of the Update Server (the <B>upclient</B> process) running
-on other machines. If no directories are specified, the
-<B>upserver</B> process distributes the contents of any directory on its
-local disk.
-<P>The <B>upserver</B> process can distribute a directory's contents
-in encrypted or unencrypted form. By default, it does not use
-encryption unless an <B>upclient</B> process requests it (this default is
-equivalent to setting the <B>-clear</B> flag). When the
-<B>-crypt</B> flag is provided, the <B>upserver</B> process only
-fulfills requests for encrypted transfer.
-<P>For the United States edition of AFS, using the <B>-crypt</B> flag
-guarantees that the <B>upserver</B> process transfers a directory's
-contents only in encrypted form. For the international edition, using
-the <B>-crypt</B> flag completely blocks data transfer, because the
-international edition of the <B>upclient</B> process cannot request
-encrypted transfer (the <B>upclient</B> initialization command does not
-include the <B>-crypt</B> flag).
-<P>The <B>upclient</B> and <B>upserver</B> processes always mutually
-authenticate, whether or not the data they pass is encrypted; they use
-the key with the highest key version number in the
-<B>/usr/afs/etc/KeyFile</B> file to construct a server ticket for mutual
-authentication.
-<P><STRONG>Cautions</STRONG>
-<P>Do not use the Update Server to distribute the contents of the
-<B>/usr/afs/etc</B> directory if using the international edition of
-AFS. The contents of this directory are sensitive and the international
-edition of AFS does not include the encryption routines necessary for
-encrypting files before transfer across the network.
-<P><STRONG>Options</STRONG>
-<DL>
-<P><DT><B><VAR>directory</VAR>
-</B><DD>Names each directory to distribute in unencrypted form (because they
-appear before the first <B>-crypt</B> or <B>-clear</B> flag on the
-command line). If this argument is omitted, all directories on the
-machine's local disk are eligible for distribution.
-<P><DT><B>-crypt
-</B><DD>Precedes a list of one or more directories that the <B>upserver</B>
-process distributes only in encrypted form.
-<P><DT><B>-clear
-</B><DD>Precedes a list of one or more directories that the <B>upserver</B>
-process distributes in unencrypted form unless the <B>upclient</B> process
-requests them in encrypted form. Use this argument only if a list of
-directories headed by the <B>-crypt</B> flag precedes it on the command
-line.
-<P><DT><B>-auth
-</B><DD>Precedes a list of one or more directories which the <B>upserver</B>
-process distributes using a form of encryption that is intermediate in
-complexity and security between the unencrypted and encrypted levels set by
-the <B>-clear</B> and <B>-crypt</B> arguments. Do not use this
-argument, because the <B>upclient</B> process does not have a
-corresponding argument that it can use to request data transfer at this
-level.
-<P><DT><B>-help
-</B><DD>Prints the online help for this command. All other valid options
-are ignored.
-</DL>
-<P><STRONG>Examples</STRONG>
-<P>The following example <B>bos create</B> command defines and starts an
-<B>upserver</B> process on the host machine
-<B>fs1.abc.com</B>. The last parameter (enclosed in
-quotes) instructs the <B>upserver</B> process to distribute the contents
-of the <B>/usr/afs/bin</B> directory in unencrypted form and the contents
-of the <B>/usr/afs/etc</B> directory in encrypted form.
-<PRE> % <B>bos create -server fs1.abc.com -instance upserver -type simple</B> \
- <B>-cmd "/usr/afs/bin/upserver /usr/afs/bin -crypt /usr/afs/etc"</B>
-</PRE>
-<P><STRONG>Privilege Required</STRONG>
-<P>The issuer must be logged in as the superuser <B>root</B> on a file
-server machine to issue the command at a command shell prompt. It is
-conventional instead to create and start the process by issuing the <B>bos
-create</B> command.
