.SH DESCRIPTION
.B dgit
treats the Debian archive as a version control system, and
bidirectionally gateways between the archive and git. The git view of
the package can contain the usual upstream git history, and will be
-augmented by commits representing uploads done without using dgit.
-This git history is stored in a canonical location

Uploads made by dgit contain an additional field

This specifies a commit (an ancestor of the dgit/suite
branch) whose tree is identical to the unpacked source upload.

+dgit push needs to canonicalise the suite name. But currently

dgit push should perhaps do `git push origin', or something similar,
by default.
currently any mechanism for determining and honouring the archive's
ideas about access control. Currently only DDs can push.
-dgit's representation of format `3.0 (quilt)' source packages (even if
-they were supported) would not represent the patch stack. Currently
-the patch series representation cannot round trip through the archive.
-Ideally dgit would represent a quilty package with an origin commit of
-some kind followed by the patch stack as a series of commits followed
-by a pseudo-merge (to make the branch fast-forwarding). This would
-also mean a new `dgit rebase-prep' command or some such to turn such a

-option to dgit push (perhaps enabled automatically) which will make
-the required pseudo-merge.

dgit's handling of .orig.tar.gz is not very sophisticated. Ideally
the .orig.tar.gz could be transported via the git repo as git tags.
+Doing this is made more complicated by the possibility of a `3.0
+(quilt)' package with multiple .orig tarballs.
The error messages are often unhelpfully terse and tend to refer to
line numbers in dgit.
The option parser requires values to be cuddled to the option name.

--dry-run often does not work with fetch, even though this is a
logically plausible request. (It fails, instead.)
