So I finished your contribution (NEWS, package documentation).

I'll take a look and will probably add it for you. I like this better
than quadprog since, according to what you formerly pointed out,
linprog really adds new functionality, sparing the user a probably not
quite obvious rearrangement of terms. Thanks.

As Nir said, having some '%!demo' or '%!test' code would be good. But
it needn't necessarily be ready before adding lsqlin. Would be good
also for quadprog.

Only to be informed, what's the current state -- Octave is rejected by
google but tries to get indirectly accepted via the FSF, have I
understood that right?
