"""Comment importer from Blogger
This python script can convert comments posted to a Blogger-powered blog to a
JSON file with can then be imported into Isso (by following the procedure
explained in docs/docs/extras/advanced-migration.rst.
The script can be run like this:
python import_blogger.py -p 'http://myblog.com/' blogger.xml out.json
where `blogger.xml` is a dump of the blog produced by the Blogger platform, and
the URL following the `-p` option is a prefix that will be applied to all post
URLs: the original host will be stripped and the path will be appended to the
string you specify here (this can be useful in the case that your blog moved to
a different domain, subdomain, or just into a new directory).
The `out.json` file is the file which will be generated by this tool, and which
can then be fed into isso:
isso -c /path/to/isso.cfg import -t generic out.json
