[racket] Information in Racket Bug Report

Dear list members,

I just received a notice that a bug report I had submitted has now
been resolved.
When I viewed the bug report.
http://bugs.racket-lang.org/query/?cmd=view&pr=12464

This was the start of the Environment section of the report.
-----------------------------------------------------
Environment:	windows "Windows NT 6.0 (Build 6002) Service Pack 2"
(win32\i386\3m) (get-display-depth) = 32
 Human Language: english

 Links: (links) = ("OCR_PROJECT" "racket-ocr"); (links #:user? #f) =
(); (links #:root? #t) = (); (links #:user? #f #:root? #t) = ()
----------------------------------------------------------

What does the Links line information mean?

C:\Users\Harry\OCR_PROJECT\racket-ocr is a directory in which I have
some Racket programs.

Thanks,
