Subject: [bug#55248] [PATCH v2 4/9] gnu: chez-scheme: Refactor documentation phases.
Date: Sun,  8 May 2022 16:07:47 -0400

Patches merged in both upstream Chez Scheme and Racket's variant will
soon let us replace the 'install-docs' phase with just
'make install-docs'.  Separating the 'link-doc-pdfs' phase (which won't
change) leaves us well-prepared for the transition, regardless of
whether Chez Scheme 9.5.10 or Racket 8.6 is released first.

* gnu/packages/chez.scm (chez-scheme)[arguments]: Split 'install-doc'
phase into 'install-docs' (matching the future 'make' target) and
'link-doc-pdfs'.
