[draft - this is based on my experience, comments from ubf, encline and clotnet developers would be nice]
Here you are :)
Short Version:
$ tla make-archive --listing \ 'PROJECT-NAME@common-lisp.net--YEAR' \
'sftp://LOGIN@common-lisp.net/project/PROJECT-NAME/public_html/PROJECT-NAME@ common-lisp.net--YEAR'
Just as a suggestion, tla 1.2 could sign archives, so the proposition of '--signed' usage and reference to http://wiki.gnuarch.org/moin.cgi/Signing_20Archives could be added.
And (just personally!) I don't think that --YEAR is a "right thing" (I know that it's recommended by Tom, but...)
