Ah yes. Good point...

Will do that.

Well, you can define filter types either in the configuration file or
in pure python code (see afew/filters). To use them, you need to
create instances of these types.

The config file is just another way of defining python classes and
creating objects. See afew/ for details.

They create two objects (ShitFilter.0 and ShitFilter.1) of type
ShitFilter (defined in line 32-33). ShitFilter inherits from
SpamFilter and adjusts the message field. ShitFilter.1 also customizes
the message.

Is your new tag called 'is:new'? Mine is just called 'new'. That could
be a problem since 'new' as tag for new mails is currently hardcoded
at various locations. I thought it was universally accepted, but then
again hardcoding these things is obviously a bad practice...
