-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.

Declare that you are deliberately doing
.IR something .
This can be used to override safety catches, including safety catches
-which relate to distro-specific policies. The meanings of
+which relate to distro-specific policies.
+The use of --deliberately is declared and published in the signed tags
+generated for you by dgit,
+so that the archive software can give effect to your intent,
+and
+for the benefit humans looking at the history.

fixing up, dgit push will fail.
.TP
-.BR --quilt=gbp " | " --quilt=dpm " | " --quilt=unapplied
+.BR -- [ quilt= ] gbp " | " -- [ quilt= ] dpm " | " --quilt=unapplied
Tell dgit that you are using a nearly-dgit-compatible git branch,
aka a
.BR "maintainer view" ,
and
do not want your branch changed by dgit.
-.B --quilt=gbp
+.B --gbp
+(short for
+.BR --quilt=gbp )
is for use with git-buildpackage.
Your HEAD is expected to be
a patches-unapplied git branch, except that it might contain changes
to upstream .gitignore files. This is the default for dgit gbp-build.
-.B --quilt=dpm
+.B --dpm
+(short for
+.BR --quilt=dpm )
is for use with git-dpm.
Your HEAD is expected to be
a patches-applied git branch,
and you aren't too lucky, dgit will notice the problem and stop,
with a useful hint.

+.BR -d "\fIdistro\fR | " --distro= \fIdistro\fR
+Specifies that the suite to be operated on is part of distro
+.IR distro .
+This overrides the default value found from the git config option
+.BR dgit-suite. \fIsuite\fR .distro .
+The only effect is that other configuration variables (used

+
+If your suite is part of a distro that dgit already knows about, you
+can use this option to make dgit work even if your dgit doesn't know
+about the suite. For example, specifying
+.B -ddebian
+will work when the suite is an unknown suite in the Debian archive.
+
+To define a new distro it is necessary to define methods and URLs
+for fetching (and, for dgit push, altering) a variety of information both
+in the archive and in dgit-repos.
+How to set this up is not yet documented.
+.TP
+.BI -C changesfile
+Specifies the .changes file which is to be uploaded. By default
+dgit push looks for single .changes file in the parent directory whose
+filename suggests it is for the right package and version.
+
+If the specified

+the value for
+.BR --build-products-dir ;

+default, in
+.BR .. ).
+.TP
+.B --rm-old-changes
+When doing a build, delete any changes files matching

+before starting. This ensures that
+dgit push (and dgit sbuild) will be able to unambigously
+identify the relevant changes files from the most recent build, even

.BI --existing-package= package
dgit push needs to canonicalise the suite name. Sometimes, dgit
lacks a way to ask the archive to do this without knowing the

pathname.

+.B --force-unrepresentable

+dgit thinks that your git tree contains changes
+(relative to your .orig tarballs)
+which dpkg-source is not able to represent.
+Your build or push will probably fail later.

+Carry on despite dgit not understanding your source package format.
+dgit will probably mishandle it.

+Do not check whether .dsc and .changes match.
+The archive will probably reject your upload.

.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
environment variables. Consult the documentaton for those programs
for details.
.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
+fast-forwarding branch containing pseudo-merges
+back into a rebasing patch stack.
+It might have to leave a note
+for a future dgit push.
+
+If the dgit push fails halfway through,
+it is not necessarily restartable and
+idempotent.
+It would be good to check that the proposed signing key is
available before starting work.
-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.
