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 1.0.0

... ... ... ... ... ... 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 field, but no field, your will be used as the comment's . An exception is raised if conflicts with an existing comment. Bugs do not have a permantent alt-id, so they the s you specify are not saved. The 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, author=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, author=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, author=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 ...
