'''Problem:''' people want to know things about packages other than version and load script.

Who wrote this?

When was it released?

Where was it downloaded?

What variant is it?	(or is this TIP 59?)

'''Solution'''  store/retrieve name-value pairs

[['''package about''' ''$package $version'']] - return the metadata names stored for ''$version'' of ''$package''

[['''package about''' ''$package $version $name'']] - return the metadata value of ''$name'' for ''$version'' of ''$package''

[['''package about''' ''$package $version $name $value'']] - set the ''$value'' of ''$name'' for ''$version'' of ''$package''


'''Alternative name?:''' [['''package meta''']]

No required names; let conventions arise

'''Discussion:'''

How do package variants share a single metadata?

When does metadata need to be available?  Only after loading a package?  Or earlier?

If earlier, [['''package about''']] calls need to go in index scripts, and automatic
indexers should be able to place them there.

Does this complement or compete with TIP 59?  If compete, who wins?
