ELPA and EmacsWiki Updates

[Nordlöw]

I am using a lot of Emacs Extensions from EmacsWiki for example the
brilliant Icicles. Can ELPA or some other package automatically
synchronize/update my copies of these extensions with some nice Emacs
Package? When I do elpa-refresh-contents() and then elpa-list-
packages() I "only" get the extensions given below. Can I add
repositories to elpa as I can I can with apt?

Thanks in advance,
Nordlöw
