+.SH FILES IN THE SOURCE PACKAGE BUT NOT IN GIT
+This section is mainly of interest to maintainers who want to use dgit
+with their existing git history for the Debian package.
+
+Some developers like to have an extra-clean git tree which lacks files
+which are normally found in source tarballs and therefore in Debian
+source packages.  For example, it is conventional to ship ./configure
+in the source tarball, but some people prefer not to have it present
+in the git view of their project.
+
+dgit requires that the source package unpacks to exactly the same
+files as are in the git commit on which dgit push operates.  So if you
+just try to dgit push directly from one of these extra-clean git
+branches, it will fail.
+
+As the maintainer you therefore have the following options:
+.TP
+\(bu
+Persuade upstream that the source code in their git history and the
+source they ship as tarballs should be identical.  Of course simply
+removing the files from the tarball may make the tarball hard for
+people to use.
+.IP
+One answer is to commit the (maybe autogenerated)
+files, perhaps with some simple automation to deal with conflicts and
+spurious changes.  This has the advantage that someone who clones
+the git repository finds the program just as easy to build as someone
+who uses the tarball.
+.TP
+\(bu
+Have separate git branches which do contain the extra files, and after
+regenerating the extra files (whenever you would have to anyway),
+commit the result onto those branches.
+.TP
+\(bu
+Provide source packages which lack the files you don't want
+in git, and arrange for your package build to create them as needed.
+This may mean not using upstream source tarballs and makes the Debian
+source package less useful for people without Debian build
+infrastructure.
+.LP
+Of course it may also be that the differences are due to build system
+bugs, which cause unintended files to end up in the source package.
+dgit will notice this and complain.  You may have to fix these bugs
+before you can unify your existing git history with dgit's.
