You're right, the man page wasn't clear about it. I've fixed it - thanks.

I must admit I've never used --noheader with anything but the default 
(list) option. The idea was really to get a list of all patches in an 
easily parseable format (which is configurable by the format option as 
well) to be used in a wrapper. It never occurred to me that it could be 
used with --download/--install.

This also brings up one of the things on my ToDo list - pca should 
return useful exit codes; two of them could be "reboot/reconfigure 
required". As it is now, you will have to parse pca's output in your 
wrapper.

Martin.
