You shouldn't need that, but if you have it, it means you are using the
version of Tramp from Emacs.  If you have an older version of Emacs, my
netrc changes won't matter.  You need the latest CVS snapshot,

With my changes, you'd have this in ~/.authinfo.gpg:

machine login ussir001 password XXX

where .authinfo.gpg is normally encrypted by the EPA library (also part
of the latest Emacs from CVS).  To get my changes, though, you need the
latest Emacs from CVS (for auth-source.el and netrc.el in addition to
Tramp itself).  Otherwise, keep using the setup above since it works for
you :)

The `gnus' function loads ~/.gnus.el (or whatever `gnus-init-file'
says), that's why it works transparently.

You can do the same with Tramp by explicitly loading ~/.tramp.el but
it's not automatic AFAIK.  Tramp's configuration is mostly controlled by
variables you can customize, so like most other Emacs packages users are
expected to keep the configuration in their Emacs custom file.  I
actually recently discussed (I was in favor) a proposal by Drew Adams in
the Emacs development list that users should be able to say "put every
customized variable that's from package X into file Y," but it didn't go
