Thanks, I fixed it slightly.

Btw, it is a bit strange in my eyes that this chapter talks about
package organization conventions on ELPA without ever mentioning that
those conventions are specific for ELPA, nor even describing what ELPA
is until a later section.  Perhaps the organization of the chapter
should be rethought, given that it no longer describes only
package.el, but also the conventions and requirements for submitting
packages to ELPA.
