+dgit can synthesize a combined view of several underlying suites.
+This is requested by specifying, for
+.I suite,
+a comma-separated list:
+.IR mainsuite \fB,\fR subsuite ...
+This facility is available with dgit clone, fetch and pull, only.
+dgit will fetch the same package from each specified underlying suite,
+separately (as if with dgit fetch).
+dgit will then generate a pseudomerge commit
+on the tracking branch
+.BI remotes/dgit/dgit/ suite
+which has the tip of each of the underlying suites
+as an ancestor,
+and which contains the same as the suite which
+has the highest version of the package.
+The package must exist in mainsuite,
+but need not exist in the subsuites.
+If a specified subsuite starts with
+.B -
+then mainsuite is prepended.
+So, for example,
+.B stable,-security
+means to look for the package in stable, and stable-security,
+taking whichever is newer.
+If stable is currently jessie,
+dgit clone would leave you on the branch
+.BR dgit/jessie,-security .
+Combined suites are not supported by the dgit build operations.
+This is because those options are intended for building for
+uploading source packages,
+and look in the changelog to find the relevant suite.
+It does not make sense to name a dgit-synthesised combined suite
+in a changelog,
+or to try to upload to it.
+When using this facility, it is important to always specify the
+same suites in the same order:
+dgit will not be make a coherent fast-forwarding history
+view otherwise.
+The history generated by this feature is not normally suitable
+for merging back into upstreams,
+as it necessarily contains unattractive pseudomerges.
