37 ;; The idea:
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
38 ;; A new XEmacs lisp-only release is generated with the following steps:
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
39 ;; 1. The maintainer runs some yet to be written program that
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
40 ;; generates all the dependency information. This should
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
41 ;; determine all the require and provide statements and associate
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
42 ;; them with a package.
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
43 ;; 2. All the packages are then bundled into their own tar balls
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
44 ;; (or whatever format)
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
45 ;; 3. Maintainer automatically generates a new `package-get-base'
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
46 ;; data structure which contains information such as the
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
47 ;; package name, the file to be retrieved, an md5 checksum,
85a06df23a9a Import from CVS: tag r20-5b16

48 ;; etc (see `package-get-base').
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
49 ;; 4. The maintainer posts an announcement with the new version
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
50 ;; of `package-get-base'.
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
51 ;; 5. A user/system manager saves this posting and runs
85a06df23a9a Import from CVS: tag r20-5b16
cvs
parents:
diff changeset
52 ;; `package-get-update' which uses the previously saved list
