# The targets below are concerned with the release process and

# Steps for making a release:
#
# 0) check
#    Run tests using ERT tool.  Not necessary but strongly suggested before a
#    release.
#
# 1) change-history
#    Update the ChangeLog file.
#
# 2) release-commit TAG=<tag> COMMITTER=<committer>
#    Tag the release.
#    Pass `COMMITTER=<committer>' argument only if it is different from
#    your git name and email.  `<committer>' should be in the form
#        "John Doe  <john.doe@example.com>"
#
# 3) dist TAG=<tag>
#    Create the tar ball and other release files and put them into $FTPDIR.
#
# 4) xemacs-package TAG=<tag>
#    Create the precompiled XEmacs package.
#
# 5) windows-package WEMACSVER=<emacs-version> TAG=<tag>
#    Create the precompiled AUCTeX package for Windows.
#    This requires a compiled Emacs of the same version at location $WEMACS.
#    NOTA BENE: you may need to use bash shell for this recipe to work.
#
# 6) release-sign TAG=<tag>
#    Sign the tar ball and create directive files for upload.  NOTA BENE: you
#    may need to use bash shell for this recipe to work.
#
# 7) release-upload
#    Upload files to GNU FTP server.
#
# 8) www-doc TAG=<tag>
#    Create documentation for AUCTeX home page.
#
# 9) preview-ball TAG=<tag>
#    Create preview package.  (Not for GNU FTP server but for CTAN.)
