Spotlight plugin for MailSpool

Introduction

This is a Spotlight plugin for the mail folder of MH or Gnus nnml backend. It extracts metadata from numbered files under Mail directory, and imports the metadata into Spotlight database.

It uses Ruby interpreter to extract metadata. So you can easily customize the extraction to edit GetMetadataForFile.rb file. But processing is slightly heavy because of Ruby.

To parse mails, it includes TMail library. To parse HTML mails, it includes ymHTML library.

Version 0.1.4u supports Universal Binary. It will work on Intel Mac (2008-01-06).
