Format: https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/ Upstream-Name: chez-srfi Source: https://github.com/arcfide/chez-srfi Files-Excluded: %3a38/with-shared-structure.ironscheme.sls Comment: The SRFI process declares, since relatively recently, that the license of SRFIs shall be the Expat license. Much of the code in this project is taken verbatim from SRFI reference implementations. . All SRFI documents carry a copyright notice and license, typically the Expat license, but some reference implementations lack explicit notices. Here is how that situation is intended to be interpreted: . > From: "Arthur A. Gleckler" > Date: Sun, 26 Jan 2020 09:47:36 -0800 > Message-ID: > Subject: Re: SRFI licenses > To: "Göran Weinholt" > Cc: SRFI Editors > > On Sun, Jan 26, 2020 at 4:25 AM Göran Weinholt wrote: > > In particular I would like to know if, given that a SRFI document > carries this license, is it implied that the reference implementation > also is covered by the same license if there is nothing else written > in the files? > > Yes, that is the intent. > > — Arthur A. Gleckler, SRFI Editor . Please note that the code written by Andrew W. Keep has the license text only in the "%3aNN.sls" file, omitting it from the "%3aNN/*" files for brevity.
