what is cas_crontab?

[Harry Putnam]

Seems to be dirth of info about the cas_crontab pkg.  All the info at 

http://www.opencsw.org/package/cas_crontab/  is nice and useful, its
just that it doesn't really tell you what it is.

I mean, I can understand brevity but:
`Class action script crontab' is a tad bit thin for a `Description'

So clicking on the Documentation link I hoped to figure it out from
there. It just says:

  "Please visit OpenCSW Manual"

OK, fine.  Visiting the online version has a handy search box so:
Typed in cas_crontab.  

  `Your search did not match any documents'

OK, trying CSWcas_crontab

 Same result.

So, what does a `Class action script crontab' do?
