Hi John,
(cc to cig-mc)

Thanks for bringing up the issue. The manual might be unclear to this
point: the *.cfg files cannot be used as input file for the non-pyre
version. The example inputs for non-pyre version are under examples/Full
and examples/Regional.

All input parameters have sensible default values in pyre version, and
the *.cfg input file only specifies the changed parameters. However,
some of the default values in non-pyre version are either not defined or
not sensible, and must be overridden by input. For backward
compatibility reason, we cannot change the default values in the
non-pyre version. As a result, when you use *.cfg as the input file for
non-pyre version, it will complain about missing parameters and might
use the wrong default values.

Also, the error in Cookbook8 is because the parser of non-pyre version
doesn't allow space characters in the "name=value" string, but the pyre
version allows.


Cheers,
