+For Fossil repositories, the module @code{(guix fossil-download)} defines

+for support of the Fossil @abbr{SCM, software configuration management} system.
+
+@deffn {Procedure} fossil-fetch ref hash-algo hash [name]
+Return a fixed-output derivation that fetches @var{ref}, a
+@code{<fossil-reference>} object.  The output is expected to have recursive
+hash @var{hash} of type @var{hash-algo} (a symbol).  Use @var{name} as
+the file name, or a generic name if @code{#f}.
+@end deffn
+
+@deftp {Data Type} fossil-reference
+This data type represents a Fossil reference
+for @code{fossil-fetch} to retrieve.
+
+@table @asis
+@item @code{uri} (type: string)
+The URI of a Fossil repository to clone, in one of the following forms,
+in which @code{[...]} denotes optional elements:
+
+@table @code
+@item http[s]://[userid[:password]@@]host[:port][/path]
+A HTTP/HTTPS URL.
+@item [file://]path/to/repo.fossil
+A file URI, where the path must have an extra leading @code{/}
+to use an absolute path (without the URI scheme, the repository
+is opened directly without cloning).

-passes just because it happens to run after an unrelated test that leaves the
-system in a favourable state.  The plugin allows user to control the level of
-randomness they want to introduce and to disable reordering on subsets of
-tests.  Tests can be rerun in a specific order by passing a seed value
