<html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hello, I have been trawling through the packages at:     <a class="moz-txt-link-freetext" href="http://pkg.racket-lang.org">http://pkg.racket-lang.org</a> And have found that very few of the packages have any licensing information and are effectively proprietary software, despite what their authors may have intended.  I can therefore study them, but not use them without breaking copyright law.  For a hobbyist this is easy enough to overlook, but for anyone wanting to use Racket commercially this means that most of the packages are unusable without contacting the authors and seeing what terms they are prepared to license their code under. This is a big enough pain for packages outside the main distribution, but I have also noticed that packages in the main distribution do not contain licence information either.  A typical example is:     <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> <a href="https://pkg.racket-lang.org/info/html-lib">https://pkg.racket-lang.org/info/html-lib</a> In html/html.rkt, it contains:     copyright by Paul Graunke June 2000 AD But has no licensing info anywhere in the package.  This was presumably LGPL code that was extracted to a package from the main racket repository.  Without that licensing information it contravenes the terms of the LGPL and more importantly, to me, means I can't use it as it hasn't been licensed for use by anyone through that package.
