6.9. Summary

The Summary header content is a short phrase summarizing the
article's content:

     Summary-content = nonblank-text

As with the subject, no restriction is placed on the content
since it is intended solely for display to humans.

     NOTE: Reading agents should be aware that the Sum-
     mary  header  is often used as a sort of secondary
     Subject header,  and  (if  present)  its  contents
     should  perhaps  be  displayed when the subject is
     displayed.

The summary SHOULD be terse.  Posters SHOULD avoid trying to
cram  their  entire  article into the headers; even the sim-
plest query usually benefits from a sentence or two of elab-
oration  and context, and not all reading agents display all
headers.
