Site links such as /?p=1234 are imported *as is* and maybe do work in
Isso. Do not use a query-based URL structure as permalinks. Ever.
Also, depending on the pages you are going to export, WXR' XML namespace
may change from ../export/1.0/ to ../export/1.2/. Isso tries to import
any WXR 1.x
When using Gunicorn or uWSGI to run `isso.dispatch` it would
automatically initialize and a default Isso instance (and cause
several logging messages), although never used.
If you use uWSGI or Gunicorn, you have to change the module from
`isso` to `isso.run`.
