Re: [Bigsister-general] plugin for environmental variables

["Peter Varlien" <suppressed>]

Tom posted a multi-part tutorial on writing requester modules to the  
BigSister-devel list a while back, I think it was early 2006. You should  
look back through the list archives.

(Indeed, this thread probably belongs on that list, rather than the  
general list.)
