Copy the script to the machine where paperless is running. Run it with
the following arguments:
1. URL of Docspell, including http(s)
2. Username for Docspell, possibly including Collective (if other name as user)
3. Password for Docspell
4. Path to Paperless' database file (`db.sqlite3`). When using Paperless with docker, it is in the mapped directory `/usr/src/paperless/data`
5. Path to Paperless' document base directory. When using Paperless with docker, it is the mapped directory `/usr/src/paperless/media/documents/origin/`
Some settings can be changed inside the script, right at the top:
*`LIMIT="LIMIT 0"` (default: inactive): For testing purposes, limits
the number of tags and correspondents read from Paperless (this will
most likely lead to warnings when processing the documents)
*`LIMIT_DOC="LIMIT 5"` (default: inactive): For testing purposes,
limits the number of documents and document-to-tag relations read
