38 ;; comments here because there are some nifty ideas here.
41 ;; A new XEmacs lisp-only release is generated with the following steps:
42 ;; 1. The maintainer runs some yet to be written program that
43 ;; generates all the dependency information. This should
44 ;; determine all the require and provide statements and associate
45 ;; them with a package.
46 ;; 2. All the packages are then bundled into their own tar balls
47 ;; (or whatever format)
48 ;; 3. Maintainer automatically generates a new `package-get-base'
49 ;; data structure which contains information such as the
50 ;; package name, the file to be retrieved, an md5 checksum,
51 ;; etc (see `package-get-base').
52 ;; 4. The maintainer posts an announcement with the new version
53 ;; of `package-get-base'.
54 ;; 5. A user/system manager saves this posting and runs
55 ;; `package-get-update' which uses the previously saved list
56 ;; of packages, `package-get-here' that the user/site
57 ;; wants to determine what new versions to download and
60 ;; A user/site manager can generate a new `package-get-here' structure
61 ;; by using `package-get-setup' which generates a customize like
62 ;; interface to the list of packages. The buffer looks something
65 ;; gnus - a mail and news reader
68 ;; [] Required by other [packages]
74 ;; [] Required by other [packages]
76 ;; Where `[]' indicates a toggle box
78 ;; - Clicking on "Always install" puts this into
79 ;; `package-get-here' list. "Needs updating" indicates a new
80 ;; version is available. Anything already in
81 ;; `package-get-here' has this enabled.
82 ;; - "Required by other" means some other packages are going to force
83 ;; this to be installed. Clicking on [packages] gives a list
84 ;; of packages that require this.
86 ;; The `package-get-base' should be installed in a file in
87 ;; `data-directory'. The `package-get-here' should be installed in
88 ;; site-lisp. Both are then read at run time.
91 ;; - Implement `package-get-setup'
92 ;; - Actually put `package-get-base' and `package-get-here' into
93 ;; files that are read.
94 ;; - SOMEONE needs to write the programs that generate the
95 ;; provides/requires database and makes it into a lisp data
96 ;; structure suitable for `package-get-base'
97 ;; - Handle errors such as no package providing a required symbol.
98 ;; - Tie this into the `require' function to download packages

894 md5sum The md5sum of filename.
895 size The size in bytes of filename.
896 provides A list of symbols that this package provides.
