A Snow repository is a list of zero or more packages and/or sibling repositories. The snow-fort repository lives at https://snow-fort.org/s/repo.scm, but clients may maintain their own lists of repositories or learn about new repos via the sibling links.
(repository
;; A sibling is a pointer to another repository, which the client may
;; choose to search as well. The URL points to a file containing
;; another `repository' sexp. The optional trust level is a real
;; number in [0..1] indicating the current repository's trust in the
;; sibling - the user's trust level is the product of all trust
;; levels along the shortest path to a source. The default is 0.5.
;;
;; Siblings may be used to build a distributed network of
;; repositories, to split the current repository into several URLs
;; for performance (e.g. moving seldom changing packages or publisher
;; lists to a repo with a longer refresh), or to provide translated
;; versions of the repo. Clients are free to ignore siblings and/or
;; maintain their own lists of repositories.
