[cups] documentation

[kalle]

The administration part of Printers is missing in the document
"Command-Line Printing and Options". Nothing written about `lpadmin' or
so. Is this purpose? Searching for command-line documentation for
printer management I found the former document "CUPS Software
Administrators Manual" (CUPS-SAM), where this was noted.
I already asked in bug #5108, why SAM is not part of the official
documentation anymore, but got insufficient answer.
Why is all this so?

Another question: does the GPL also apply to the CUPS-documentation?
