Import comments and bugs from XMLFILE.  If XMLFILE is '-', the file is
read from stdin.

This command provides a fallback mechanism for passing bugs between
repositories, in case the repositories VCSs are incompatible.  If the
VCSs are compatible, it's better to use their builtin merge/push/pull
to share this information, as that will preserve a more detailed
history.

The XML file should be formatted similarly to

where the ellipses mark output commpatible with Bug.xml() and
Comment.xml().  Take a look at the output of `be show --xml` for some
explicit examples.  Unrecognized tags are ignored.  Missing tags are
left at the default value.  The version tag is not required, but is
strongly recommended.

The bug and comment UUIDs are always auto-generated, so if you set a
<uuid> field, but no <alt-id> field, your <uuid> will be used as the
comment's <alt-id>.  An exception is raised if <alt-id> conflicts with
an existing comment.  Bugs do not have a permantent alt-id, so they
the <uuid>s you specify are not saved.  The <uuid>s _are_ used to
match agains prexisting bug and comment uuids, and comment alt-ids,
and fields explicitly given in the XML file will replace old versions
unless the --add-only flag.

*.extra_strings recieves special treatment, and if --add-only is not
set, the resulting list concatenates both source lists and removes
repeats.

Here's an example of import activity:
  Repository
   bug (uuid=B, creator=John, status=open)
     estr (don't forget your towel)
     estr (helps with space travel)
     com (uuid=C1, author=Jane, body=Hello)
     com (uuid=C2, author=Jess, body=World)
  XML
   bug (uuid=B, status=fixed)
     estr (don't forget your towel)
     estr (watch out for flying dolphins)
     com (uuid=C1, body=So long)
     com (uuid=C3, author=Jed, body=And thanks)
  Result
   bug (uuid=B, creator=John, status=fixed)
     estr (don't forget your towel)
     estr (helps with space travel)
     estr (watch out for flying dolphins)
     com (uuid=C1, author=Jane, body=So long)
     com (uuid=C2, author=Jess, body=World)
     com (uuid=C4, alt-id=C3, author=Jed, body=And thanks)
  Result, with --add-only
   bug (uuid=B, creator=John, status=open)
     estr (don't forget your towel)
     estr (helps with space travel)
     com (uuid=C1, author=Jane, body=Hello)
     com (uuid=C2, author=Jess, body=World)
     com (uuid=C4, alt-id=C3, author=Jed, body=And thanks)

Examples:

Import comments (e.g. emails from an mbox) and append to bug XYZ
  $ be-mbox-to-xml mail.mbox | be import-xml --c XYZ -
Or you can append those emails underneath the prexisting comment XYZ-3
  $ be-mbox-to-xml mail.mbox | be import-xml --c XYZ-3 -

User creates a new bug
  user$ be new "The demuxulizer is broken"
  Created bug with ID 48f
  user$ be comment 48f
  <Describe bug>
  ...
User exports bug as xml and emails it to the developers
  user$ be show --xml 48f > 48f.xml
  user$ cat 48f.xml | mail -s "Demuxulizer bug xml" devs@b.com
or equivalently (with a slightly fancier be-handle-mail compatible
email):
  user$ be email-bugs 48f
Devs recieve email, and save it's contents as demux-bug.xml
  dev$ cat demux-bug.xml | be import-xml -
