commit 63a89eb5888fb9ec5596eda8fa6c259501df7cf9
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sun Apr 3 22:03:38 2022 +1000

    doc/doc.am: Stop treating "gnu.eps" as "example".
    
    * doc/doc.am: Stop treating "gnu.eps" as an "example" file; it is also
      used by pdfmark's cover.ms, which is ordinary documentation.  We
      therefore must not omit it when building.
    
      (install-data-hook): Add dependency on new phony target,
      "install_doc_gnu_eps".
    
      (install_doc_examples): Move installation of "gnu.eps" from here...
      (install_doc_gnu_eps): ...to here.  Also refactor the loop we use to
      locate the file follow a more idiomatic pattern.
