** WEBPAGE: artifact
** WEBPAGE: file
** WEBPAGE: whatis
**
** Typical usage:
**
**    /artifact/SHA1HASH

**    /whatis/SHA1HASH
**    /file/NAME
**
** Additional query parameters:
**
**   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=".
**
** The /artifact page show the complete content of a file
** identified by SHA1HASH as preformatted text.  The
** /whatis page shows only a description of the file.  The /file
** page shows the most recent version of the named file.
