[LDM #IDM-709196]: missing man page?

Paul,

The pqinsert(1) user will have to have write-access to the product-queue -- so 
the user's group membership will have to be the same as the product-queue's and 
the product-queue will have to allow group write.

pqinsert(1) sends a SIGCONT to its process-group to tell other members of the 
group that they should check the queue for new data-products. If pqinsert(1) is 
executed outside of the LDM system, then upstream LDM processes won't 
automatically receive this signal and, consequently, won't know that the queue 
has been modified until they wake-up from their default 30 second sleep. 
Consequently, your inserted files probably won't be immediately pushed to 
downstream LDM-s.

This is why we recommend that pqinsert(1) processes be executed by a script 
that, in turn, is executed via an EXEC entry in the LDM configuration-file.

A workaround might be to use the file "~ldm/ldmd.pid" to obtain the PID of the 
LDM's process group and send the group a SIGCONT if you can. It's likely that 
the O/S will prevent this, however.
