Summary:                    RFE: Override configuration parameters on the
commandline (via --param?)
Description: 
For testing and various other purposes i sometimes fiddle with
configuration settings in pkgutil.conf. How about introducing a command
line option to do this on-the-fly?

A somewhat limited use case example to illustrate the RFE:

$ pkgutil -V | grep noncsw
noncsw          true (default: false)

Now to compare only CSW cups packages i would do

$ pkgutil -c cups | grep CSW

With --param i could also do 

$ pkgutil --param noncsw=false -c cups

and have pkgutil filter the pkg list right away. I know, it is longer to
type, but the general ability to change and test settings on the fly feels
helpful to me. I don't know whether this can be easily implemented for all
possible parameters (also future ones) so that this doesn't result in more
work when you implement additional parameters. Wishlist item.

r205 contains this feature. Actually adding this option is a good way to
hinder option creep since it makes configuration file options accessible
from the command line, otherwise people would ask for equivalent command
line options all the time, now I can refer them to -p. :-)

Due to how the parsing works these two types are the ways to specify this
option (multiples are allowed):

# pkgutil -p use_gpg:false --param=use_md5:false -V

The colon separator is the same as is used when specifying arch and
release for the --target option. Options that contain space separated items
must be quoted:

# pkgutil -p exclude_pattern:"foo bar" -V

Another way of doing what you want here is to have a custom pkgutil.conf
file that you specify with --config. I'm implementing this anyway since
it's generic functionality. I have another similar request from
http://www.opencsw.org/mantis/view.php?id=4302 as
well, he accepted this generic solution to his specific request.
