**   ln              - show line numbers
**   ln=N            - highlight line number N
**   ln=M-N          - highlight lines M through N inclusive
**   ln=M-N,Y-Z      - highlight lines M through N and Y through Z (inclusive)
**   verbose         - show more detail in the description
**   download        - redirect to the download (artifact page only)
**   name=SHA1HASH   - Provide the SHA1HASH as a query parameter
**   filename=NAME   - Show information for content file NAME
**   fn=NAME         - "fn" is shorthand for "filename"
**   ci=VERSION      - The specific check-in to use for "filename=".
