creating cfengine modules that provide verbose output

[Harry Hoffman]

Hi,

I've written a cfengine module to check for updates on my systems. It
calls, for example, yum to check for updates and sets a class if updates
are available.

What I'm wondering is if there is a good way to allow the cfengine
module to be verbose? In this case to report, perhaps via alerts, the
packages that need to be updated.

Cheers,
Harry
