It was downloaded from http://racket-lang.org/download

readline collection notes:
GNU's readline library is covered by the GPL (found at
/usr/share/common-licenses/GPL on Debian systems), and that applies to
code that links with it. PLT Scheme is LGPL, so this code is not used by
default; you should explicitly enable it if you want to. Also, be aware that
if you write code that uses this library, it will make your code link to the
readline library when invoked, with the usual GPL implications.

Note from Ari Pollak <ari@debian.org>: because the R5RS license wasn't clear
enough according to the Debian Free Software Guidelines, I asked the authors to
clarify what they meant. Here are their responses:

(Comment from David Bremner <bremner@debian.org>, apparently Eli
Barzilay did the actual questioning and collecting of answers, with the
question provided by Ari).

I got an answer back from the FSF "records" guy and he tells me that
Will Fitzgerald elevated his reference implementation of SRFI 19 to
the public domain. But this answer comes with a disclaimer:

this is not a legal opinion, nor is this a binding pronouncment of
the FSF

so I don't know if we can rely on it.
