The documentation has been updated in the CVS repository. Basically, it's just a 
matter of getting some submitted patches rolled in and tested by the users, and 
then 1.30.2 will go out. (I'm reluctant to let 1.30.2 go out without rolling in 
the various patches.)

[Developers take note: you'll want to do a "cvs update" to grab this change.]

This is a good idea. I have added a message to the *.cc programs so that, when 
queue_manager is not compiled in, it displays a message to that effect and how 
to re-compile with this support compiled in.

register.com, the registrar for gnuqueue.org, updated their software, and now 
gnuqueue.org is a deadlink (including some pages on SourceForge that try to 
reference things through gnuqueue.org). Register.com says the problem will be 
fixed within six hours (by 2AM EST) ... we'll see.

Could also be a bug; you might want to try applying one of the various patches 
that have floating around ....
