The basic idea behind Paperwork is "scan & forget" : You should be able to
just scan a new document and forget about it until the day you need it
again.
Let the machine do most of the work.

Main features are:
- Scan
- Automatic orientation detection
- OCR
- Indexing
- Document labels
- Automatic guessing of the labels to apply on new documents
- Search
- Keyword suggestions
- Quick edit of scans
- PDF support
