Prior art (package metadata)

[lassik]

The metadata file for a Snow-fort package is in a file called package.scm in the root directory of each package's tar file. The contents look like this:

(package
  (maintainers "Alex Shinn <hidden@example.com>")
  (authors "Alex Shinn <hidden@example.com>")
  (version "0.7.4.1")
  (license bsd)
  (library
    (name
      (chibi term ansi))
    (path "chibi/term/ansi.sld")
    (depends
      (scheme base)
      (scheme write)
      (scheme process-context)))
  (library
    (name
      (chibi term ansi-test))
    (path "chibi/term/ansi-test.sld")
    (depends
      (scheme base)
      (scheme write)
      (chibi term ansi))
    (use-for test))
  (manual "chibi/term/ansi.html")
  (description "A library to use ANSI escape codes to format text and background [...]")
  (test "run-tests.scm"))

(compile -s -O3 intarweb.import.scm)

(install-extension
  'intarweb
  '("intarweb.so" "intarweb.import.so")
  `((version "1.7")))

or:

(standard-extension 'foo "0.1.2")

Akku package metadata (all aggregated here) looks like this:

(package
  (name "swish")
  (versions
    ((version "0.0.0-akku.259.842f51f") (synopsis "Swish Concurrency Engine (like Erlang/Node)")
      (description
        "The Swish Concurrency Engine is a framework used to write\nfault-tolerant programs with message-passing concurrency. It uses the\nChez Scheme programming language and embeds concepts from the Erlang\nprogramming language. Swish also provides a web server."
        "This package provides swish, swish-build and swish-test. Try\nrunning swish with and enter this expression to start up a web server\nthat serves files from the ./web directory:"
        "  (parameterize ((http-port-number 8080)) (http-sup:start&link))"
        "More information, including a manual, is available on the homepage."
        "This package requires Akku 0.4.0+ and Chez Scheme 9.5.2+. It is\nquite experimental and unlike any other Akku package. Any problems or\nrequests for the packaging go to Akku's bug tracker! If installation\ndoesn't work then try to debug it with \"env AKKU_LOG_LEVEL=debug akku\ninstall\".")
