Missing license information for LaTeX files #332

Closed LiberalArtist closed 2 years ago

LiberalArtist commented 2 years ago

The scribble-lib package needs additional license information for some LaTeX code it includes. The ones I've found are:

https://github.com/racket/scribble/blob/3866ac350fb703dc64dadaa8c0112ecd163f73a1/scribble-lib/scribble/sigplan/sigplanconf.cls#L3-L24

https://github.com/racket/scribble/blob/3866ac350fb703dc64dadaa8c0112ecd163f73a1/scribble-lib/scribble/scribble.tex#L116-L127

https://github.com/racket/scribble/blob/3866ac350fb703dc64dadaa8c0112ecd163f73a1/scribble-lib/scribble/acmart/acmart.cls#L1-L22

Additionally, it looks like distributing acmart.cls requires that acmart.dtx be:

part of the same distribution. (The sources need not necessarily be in the same archive or directory.)

which it doesn't seem like we're doing, though I don't know what the definition of "distribution" is.

I'll try to deal with this unless someone else gets to it first.

I noticed this thanks to the Debian copyright file.

The license for the latest version of acmart is here; it looks a little different: https://github.com/borisveytsman/acmart/blob/primary/acmart.dtx

I think the paragraph I quoted may be added by the docstrip utility when it generates the .cls file from the .dtx file. I think it may be referring to this part of The LaTeX Project Public License:

  1. If you are not the Current Maintainer of the Work, you may distribute a Compiled Work generated from a Derived Work, as long as the Derived Work is distributed to all recipients of the Compiled Work, and as long as the conditions of Clause 6, above, are met with regard to the Derived Work.

But (while I am not a lawyer) I don't think that's what we're doing, because I don't think we are creating a Derived Work at all. I think what we're doing is covered instead by this provision:

  1. You may distribute a Compiled Work that has been generated from a complete, unmodified copy of the Work as distributed under Clause 2 above, as long as that Compiled Work is distributed in such a way that the recipients may install the Compiled Work on their system exactly as it would have been installed if they generated a Compiled Work directly from the Work.

So I don't think we need to distribute any additional files.
