This field is important; it's how people will find your package when
they're looking for things by topic area. To separate the keywords, you
can use spaces, commas, or both.
@item Package-Version
If @samp{Version} is not suitable for use by the package manager, then
a package can define @samp{Package-Version}; it will be used instead.
This is handy if @samp{Version} is an RCS id or something else that
cannot be parsed by @code{version-to-list}. @xref{Packaging Basics}.
@item Package-Requires
If this exists, it names packages on which the current package depends
for proper operation. @xref{Packaging Basics}. This is used by the
package manager both at download time (to ensure that a complete set
of packages is downloaded) and at activation time (to ensure that a
package is activated if and only if all its dependencies have been).
Its format is a list of lists. The @code{car} of each sub-list is the
name of a package, as a symbol. The @code{cadr} of each sub-list is
the minimum acceptable version number, as a string. For instance:
@smallexample
;; Package-Requires: ((gnus "1.0") (bubbles "2.7.2"))
@end smallexample
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.
@end table
Just about every Lisp library ought to have the @samp{Author} and
