+
+send changesets by email
+
+    By default, diffs are sent in the format generated by hg export,
+    one per message.  The series starts with a "[PATCH 0 of N]"
+    introduction, which describes the series as a whole.
+
+    Each patch email has a Subject line of "[PATCH M of N] ...", using
+    the first line of the changeset description as the subject text.
+    The message contains two or three body parts.  First, the rest of
+    the changeset description.  Next, (optionally) if the diffstat
+    program is installed, the result of running diffstat on the patch.
+    Finally, the patch itself, as generated by "hg export".
+
+    With --outgoing, emails will be generated for patches not
+    found in the destination repository (or only those which are
+    ancestors of the specified revisions if any are provided)
+
+    With --bundle, changesets are selected as for --outgoing,
+    but a single email containing a binary Mercurial bundle as an
+    attachment will be sent.
+
+    Examples:
+
+    hg email -r 3000          # send patch 3000 only
+    hg email -r 3000 -r 3001  # send patches 3000 and 3001
+    hg email -r 3000:3005     # send patches 3000 through 3005
+    hg email 3000             # send patch 3000 (deprecated)
+
+    hg email -o               # send all patches not in default
+    hg email -o DEST          # send all patches not in DEST
+    hg email -o -r 3000       # send all ancestors of 3000 not in default
+    hg email -o -r 3000 DEST  # send all ancestors of 3000 not in DEST
