The report class defined "cfengine" is not a valid class in the current version of cfengine. To get the report to function you need to adjust the class to read "cfengine_3". You can verify this by greping the defined classes.

"Not shown in this example is the set_config_values() bundle, which is part of the CFEngine Standard Library" |
Need clarification about CFEngine Standard Library. Only at page 66 you recommend to download the latest version of library. For beginners who uses old version of CFEngine (my is 3.2.4) it isn't clear why provided example does not work.
So need to move note about CFEngine Standard Library at least to page 32 from page 66. Or even specify at the very beginning of the book which version of CFEngine Core and COPBL was used in examples. I know that COPBL hasn't versions (hey, it really should! ;) because it's almost impossible to find which snapshot of COPBL repository included in specific CFEngine Core release) so you can specify which exactly package/tarball you used for examples.
Thanks.

the last paragraph (above the example) |
"For integers, CFEngine sup-
ports .... the
prefixes K, M and G to represent powers of 2 (that is, 1024, etc.)"
In fact, from the example "i3" uses suffix, rather than prefixes as described here.

example with ifvarclass and @(words) list |
Is'n clear why exactly class "darwin" is defined. Is this machine where example was run has hostname "darwin"? So this is hard class and it will be defined.
"Here is output on a Mac" -- why class "apple" isn't defined then? (I don't have mac to check, but I suppose that instead of hard class "linux" on Linux machines,hard class "apple" will be defined on Mac's).
As for beginner it was really hard to understand behavior of this example. Could you please clarify something in example's description?
Thanks.

description of additional agent promises in commercial editions of CFEngine |
* services: to configure Windows system services
While "services" used in the text above (for community edition of CFEngine) it will be better to say something like:
* services: additionaly has class "windows" to configure Windows system services

My first edition dead tree version has no index! IMO that's a serious problem, as one reason I love ORA books is awesome indexes.
(I talked to Diego about this a while ago, and I know why it's missing. I'm creating this because I think it *is* a serious problem and I wanted to get it on the record.)
