+Import a Debian-format source package,
+specified by its .dsc,
+into git,
+the way dgit fetch would do.
+
+This does about half the work of dgit fetch:
+it will convert the .dsc into a new, orphan git branch.
+Since dgit has no access to a corresponding source package archive
+or knowledge of the history
+it does not consider whether this version is newer
+than any previous import
+or corresponding git branches;
+and it therefore does not
+make a pseudomerge to bind the import
+into any existing git history.
+
+There is only only sub-option:
+
+.B --require-valid-signature
+causes dgit to insist that the signature on the .dsc is valid
+(using the same criteria as dpkg-source -x).
+Otherwise, dgit tries to verify the signature but
+the outcome is reported only as messages to stderr.
+
+If
+.I branch
+is prefixed with
+.B +
+then if it already exists, it will be simply ovewritten,
+no matter its existing contents.
+If
+.I branch
+is prefixed with
+.B ..
+then if it already exists
+and dgit actually imports the dsc
+(rather than simply reading the git commit out of the Dgit field),
+dgit will make a pseudomerge
+so that the result is necessarily fast forward
+from the existing branch.
+Otherwise, if branch already exists,
+dgit will stop with an error message.
+
+If
+.I branch
+does not start with refs/, refs/heads/ is prepended.
+The specified branch is unconditionally updated.
+
+If the specified .dsc contains a Dgit field,
+dgit will simply make a branch of that commit.
+If you cannot manage to find that commit anywhere,
+consider --force-import-dsc-with-dgit-field.
