-The usual workflow is:
-.br
-1. \fBdgit clone\fR or \fBfetch\fR;
-.br
-2. make, do dev tests, and commit changes in git as desired;
-.br
-3. build packages for upload, using e.g. \fBdgit sbuild\fR
-.br
-4. do pre-upload tests of the proposed upload;
-.br
-5. \fBdgit push\fR.
.SH OPERATIONS
.TP
\fBdgit clone\fR \fIpackage\fP [\fIsuite\fP] [\fB./\fP\fIdir|\fB/\fP\fIdir\fR]
.I suite
belongs.
+.I suite
+may be a combination of several underlying suites in the form
+.IR mainsuite \fB,\fR subsuite ...;
+see COMBINED SUITES in dgit(7).
+
For your convenience, the
.B vcs-git
remote will be set up from the package's Vcs-Git field, if there is
.IR suite ;
otherwise it parses debian/changelog and uses the suite specified
there.
+suite may be a combined suite, as for clone.
.TP
\fBdgit pull\fR [\fIsuite\fP]
Does dgit fetch, and then merges the new head of the remote tracking
invoking host. This allows you to do a push when the system which has
the source code and the build outputs has no access to the key:
+.TS
+l l.
1. Clone on build host (dgit clone)
-.br
2. Edit code on build host (edit, git commit)
-.br
3. Build package on build host (dgit build)
-.br
4. Test package on build host or elsewhere (dpkg -i, test)
-.br
5. Upload by invoking dgit rpush on host with your GPG key.
+.TE
However, the build-host must be able to ssh to the dgit repos. If
this is not already the case, you must organise it separately, for
implying a split between the dgit view and the
maintainer view, the pseudo-merge will appear only in the dgit view.)
.TP
+.BR --delayed =\fIdays\fR
+Upload to a DELAYED queue.
+
+.B WARNING:
+If the maintainer responds by cancelling
+your upload from the queue,
+and does not make an upload of their own,
+this will not rewind the git branch on the dgit git server.
+Other dgit users will then see your push
+(with a warning message from dgit)
+even though the maintainer wanted to abolish it.
+Such users might unwittingly reintroduce your changes.
+
+If this situation arises,
+someone should make a suitable dgit push
+to update the contents of dgit-repos
+to a version without the controversial changes.
+.TP
.BR --dgit-view-save= \fIbranch\fR|\fIref\fR
Specifies that when a split view quilt mode is in operation,
and dgit calculates
.BI --no-rm-on-error
Do not delete the destination directory if clone fails.
.TP
+.BI --dep14tag
+Generates a DEP-14 tag (eg
+.BR debian/ \fIversion\fR)
+as well as a dgit tag (eg
+.BR archive/debian/ \fIversion\fR)
+where possible. This is the default.
+.TP
+.BI --no-dep14tag
+Do not generate a DEP-14 tag, except in split quilt view mode.
+(On servers where only the old tag format is supported,
+the dgit tag will have the DEP-14 name.
+This option does not prevent that.)
+.TP
+.BI --dep14tag-always
+Insist on generating a DEP-14 tag
+as well as a dgit tag.
+If the server does not support that, dgit push will fail.

.BI -D
Prints debugging information to stderr. Repeating the option produces
more output (currently, up to -DDDD is meaningfully different).

-.SH WORKFLOW - SIMPLE
-It is always possible with dgit to clone or fetch a package, make
-changes in git (using git-commit) on the suite branch
-.RB ( "git checkout dgit/" \fIsuite\fR)
-and then dgit push. You can use whatever gitish techniques you like
-to construct the commits to push;
-the only requirement is that what you push is a
-descendant of the state of the archive, as provided by dgit in the
-remote tracking branch
-.BR remotes/dgit/dgit/ \fIsuite\fR.
-
-If you are using dgit to do an NMU (in Debian),
-and don't know about the
-maintainers' preferred packaging workflows, you should make your
-changes as a linear series of (logicially separated) commits on top of
-what's already in the archive.
-
-If you are lucky the other uploaders have also used dgit and
-integrated the other relevant git history; if not you can fetch it
-into your tree and cherry-pick etc. as you wish.
-.SH WORKFLOW - INTEGRATING BETWEEN DGIT AND OTHER GIT HISTORY
-If you are the maintainer of a package dealing with uploads made
-without dgit, you will probably want to merge the synthetic commits
-(made by dgit to represent the uploads) into your git history.
-Normally you can just merge the dgit branch into your own master, or
-indeed if you do your work on the dgit local suite branch
-.BI dgit/ suite
-you can just use dgit pull.
-
-However the first time dgit is used it will generate a new origin
-commit from the archive which won't be linked into the rest of your
-git history. You will need to merge this.
-
-If last upload was in fact made with git, you should usually proceed
-as follows: identify the commit which was actually used to build the
-package. (Hopefully you have a tag for this.) Check out the dgit
-branch
-.RB ( "git checkout dgit/" \fIsuite\fR)
-and merge that other commit
-.RB ( "git merge debian/" \fIversion\fR).
-Hopefully this merge will be trivial because the two trees should
-be very similar. The resulting branch head can be merged into your
-working branches
-.RB ( "git checkout master && git merge dgit/" \fIsuite\fR).
-
-If last upload was not made with git, a different approach is required
-to start using dgit. First, do
-.B dgit fetch
-(or clone) to obtain a git history representation of what's in the
-archive and record it in the
-.BI remotes/dgit/dgit/ suite
-tracking branch. Then somehow, using your other git history
-plus appropriate diffs and cherry picks from the dgit remote tracking
-branch, construct a git commit whose tree corresponds to the tree to use for the
-next upload.
-
-between what's in the archive and what you intend to upload.
-Then run
-.BR "dgit push"
-to actually upload the result.
-
-If the commit-to-be-uploaded is not a descendant of the
-dgit remote tracking branch, you will need to pass
-.B --overwrite
-to dgit.
.SH CONFIGURATION
dgit can be configured via the git config system.
You may set keys with git-config (either in system-global or per-tree
Specifies the distro for a suite. dgit keys off the suite name (which
appears in changelogs etc.), and uses that to determine the distro
which is involved. The config used is thereafter that for the distro.

.SH BUGS
-dgit's git representation of format `3.0 (quilt)' source packages does
-not represent the patch stack as git commits. Currently the patch
-series representation cannot round trip between git and 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
-fast-forwarding branch back into a rebasing patch stack, and a `force'
-option to dgit push (perhaps enabled automatically by a note left by
-rebase-prep) which will make the required pseudo-merge.
-
-If the dgit push fails halfway through, it should be restartable and
-idempotent. However this is not true for the git tag operation.
-Also, it would be good to check that the proposed signing key is
+There should be
+a `dgit rebase-prep' command or some such to turn a

+It might have to leave a note
+for a future dgit push.

-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.
-
-dgit's build functions, and dgit push, should not make any changes to
+dgit's build functions, and dgit push, may make changes to
your current HEAD. Sadly this is necessary for packages in the `3.0
(quilt)' source format. This is ultimately due to what I consider
design problems in quilt and dpkg-source.
-There should be an option which arranges for the `3.0 (quilt)'
-autocommit(s) to not appear on your HEAD, but instead only in the
-remote tracking suite branch.
-
--dry-run does not always work properly, as not doing some of the git
fetches may result in subsequent actions being different. Doing a
non-dry-run dgit fetch first will help.
+--damp-run is likely to work much better.
