Packages that don't need to support Emacs versions older than Emacs 27
can have the @samp{Package-Requires} header split across multiple
lines, like this:
@smallexample
@group
;; Package-Requires: ((emacs "27.1")
;; (compat "29.1.4.1"))
@end group
@end smallexample

Note that with this format, you still need to start the list on the
same line as @samp{Package-Requires}.
The package code automatically defines a package named @samp{emacs}
with the version number of the currently running Emacs. This can be
used to require a minimal version of Emacs for a package.
