**
**     "latest"   means use the most recent check-in for the document
**                regardless of what branch it occurs on.
**
** FILE is the name of a file to delivered up as a webpage.  FILE is relative
** to the root of the source tree of the repository. The FILE must
** be a part of CHECKIN, except when CHECKIN=="ckout" when FILE is read
** directly from disk and need not be a managed file.  For /uv, FILE
** can also be the hash of the unversioned file.
**
** The "ckout" CHECKIN is intended for development - to provide a mechanism
** for looking at what a file will look like using the /doc webpage after
** it gets checked in.
**
** The file extension is used to decide how to render the file.
