Some version control systems provide automated handling of quite a

That is a keyword string, as used by the CVS version control system.
On page 79 of the Cederqvist¹, we see:
»
CVS can use a mechanism known as keyword substitution (or keyword
expansion) to help identifying the files. Embedded strings of the
form $keyword $ and $keyword :...$ in a file are replaced with
strings of the form $keyword :value $ whenever you obtain a new
revision of the file.

$Revision$
The revision number assigned to the revision.

That suggests the original file may have been maintained in CVS, and
since then used raw, as might happen when individual users maintain
their own copy. (More recent versioning tools might have copied the
string - I don't know what git, mercurial, and the rest of the crowd
do.)

years ago.)
