Here is an overview of the files:
+compface.el
+
+ Provides the ELisp-based uncompface program. It is excellent
+ and practical (actually you can replace lisp/compface.el with
+ it), however the author is missing and the copyright has not
+ been assigned yet.
+
gnus-namazu.el
This file defines the command to search mails and persistent
one-line-cookie.diff
+sendmail.el
+smtpmail.el
+
+ Copies of the corresponding files from the Emacs lisp/mail/
+ directory, to provide features (occasionally) needed by Gnus which
+ may not be provided by the versions of these files in older Emacs
+ distributions. XEmacs users should NOT use this, since it doesn't
+ work. See the XEmacs mail-lib module instead.
+
ssl.el
+ Obsolete interface to OpenSSL. Completely replaced by
+ lisp/tls.el, which supports both GnuTLS and OpenSSL. This
+ file will be removed eventually.
+
