;;; Commentary:

;; Manipulate packages for the netinstall setup utility

;; The process should be so:

;; 1. The package maintainer or release manager makes a release
;; announcement.
;;
;; 2. For a new package releases the netinstall maintainer simply
;; needs to update `ftp://ftp.xemacs.org/pub/xemacs/setup.ini'. This is
;; harder than it sounds because the file also includes information
;; about the binary releases. At the moment going to the netinstall
;; directory and typing:
;;
;;   `make XEMACS=<current executable location> setup.ini'
;;
;; will do the right thing provided that:
;;
;; (a) `package-net-cygwin32-binary-size' and
;; `package-net-win32-binary-size' are set correctly.
;;
;; (b) The binary pointed to by `XEMACS' has a current
;; `package-index.LATEST.pgp' file. If you don't specify the XEMACS=
;; part then you will get whatever is current for your build tree -
;; which is probably not what you want.
;;
;; You can run `package-net-convert-index-to-ini' manually and specify
;; REMOTE but I generally found that to be inconvenient and error-prone.
;;
;; 3. For package releases that's all you need to do. For binary
;; releases you need to build both cygwin and win32 binaries and put
;; them in appropriate tarballs: This can be achieved by running
;; build-msw-release.sh
;;

(require 'package-admin)

;; What path should we use from the myriad available?
;; For netinstall we just want something simple, and anyway this is only to
;; bootstrap the process. This will be:
;; <root>/setup/ for native windows
;; <root>/lib/xemacs/setup for cygwin.
;;
;;; To Do:
;;
;; 1. Package update functions should also update the installed
;; database so that running setup.exe again does not reinstall
;; packages.
;;
;; 2. Generating setup.ini should be more automatic.
