The "/finfo" page:
Usage:
- /finfo?name=FILENAME
 - /finfo?name=FILENAME&ci=HASH
 
Show the change history for a single file. The name=FILENAME query parameter gives the filename and is a required parameter. If the ci=HASH parameter is also supplied, then the FILENAME,HASH combination identifies a particular version of a file, and in that case all changes to that one file version are tracked across both edits and renames. If only the name=FILENAME parameter is supplied (if ci=HASH is omitted) then the graph shows all changes to any file while it happened to be called FILENAME and changes are not tracked across renames.
Additional query parameters:
- a=DATETIME
 - Only show changes after DATETIME
 - b=DATETIME
 - Only show changes before DATETIME
 - ci=HASH
 - identify a particular version of a file and then track changes to that file across renames
 - m=HASH

 - n=NUM
