The credits file is an RFC-4180-compliant CSV file with 5 columns.
The first column (column 1) is always 1 letter long and is the row type.
The row type determines the meaning of the other columns.
The following row types are supported:
* E: Credits entry
* Column 2: Task/contribution
* Column 3: Contributor name
* Column 4: Contributor e-mail
* Column 5: Contributor nickname
* M: Alternative credits entry that is a placeholder for other or unknown authors
* Columns 2-5: Unused
* S: Section
* Column 2: Section name
* Columns 3-5: Unused
* U: Subsection
* Column 2: Subsection name
* Columns 3-5: Unused
Columns 2, 3 and 5 MUST be in US-ASCII.
