Shared Variables
----------------

The info files also allow certain variables to be expanded at runtime.
To expand a variable, precede it with a dollar sign (and put it in curly
braces just to be safe).  Here are the variables CVS knows about:

   * ${CVSROOT} - The top of the repository.

   * ${RCSBIN} - (Obsolete) Don't use this variable.  It is only
     applicable in CVS Version 1.9.18 and older.  Specifying it now may
     result in an error.

   * ${CVSEDITOR} ${VISUAL} ${EDITOR} - These all expand to the editor
     that CVS is using for a log message.

   * ${USER} - The user running CVS (on the server side).
