Changes between 0.9.1 and 0.9.2.  This list is certainly incomplete.

 - Added support for pgp 5's DSA and ElGamal keys.

 - Added support to short-circuit the normal output paths in
pksclient, and instead output indexes and keys directly to stdout.
This saves a lot of virtual memory.

 - Removed many gmake-isms from the Makefile.

 - In the index pages from the web server, links in the User ID look
up by KeyID instead of name, to eliminate ambiguity.

 - Fixed defunct process leak on some platforms, notably solaris.

 - Check for and, if necessary, use bsd4.2/ultrix 2-argument openlog.

 - The help files now must have a (possibly empty) MIME header block.
This allows help files to use non-ascii character sets.

 - keyrings returned by the mail server have content-type
application/pgp-keys, as per rfc2015.

 - fixed a double-memory-free.

 - pksd is more careful about shutting down cleanly when it receives a
non-fatal signal (INT, QUIT, HUP, TERM).
