Subject: [PATCH v2 05/20] gnu: Add ruby-latex-decode.

From: Philip McGrath <[email-masked]>
Date: Mon, 25 Jul 2022 11:10:06 -0400

* gnu/packages/ruby.scm (ruby-latex-decode): New variable.
---
Just about an hour after I sent this patch series, the upstream
maintainer of 'ruby-latex-decode' released a v0.4.0 incorporating the
patches I'd sent---so, here is a v2 of just this patch! I can re-send
the rest of the series if you want, but it seemed like that would be
more confusing.
