Converter for TypePad

I’ve been working on a converter that takes a TypePad export file and
converts it to Typo. I had this working for the latest stable
version, but then decided I wanted the latest SVN version. I’m having
a hard time finding what I need to include in my hash when calling
Content.create. The current version of my script is attached. Below
are the errors I’m getting.

Any help you can provide is appreciated.

[typo/db/converters]$ ./typepad.rb --help
Usage: typepad.rb [options]
-f, --file FILE Path to TypePad export file.
-b, --blogname BLOGNAME Name of blog defined in Typo.
-h, --help Show this message.
[typo/db/converters]$ ./typepad.rb -f ~/export.txt -b justinj.org
