cl-installer: installing everything but dev components

Hi,
I already told about this problem.

When you generate a QPR, you make a collection of core, slib, and dev
qp[mk] files.
When you want to install that qpr, you may open the qpr and choose if
you want to install the dev components or not.
But, if you use ‘cl-installer -i’ from shell or within a script, you
cannot choose if you want to install the dev components or not and
generally, the answer is ‘not’.
So, it would be very usefull to have a supplementary option in
cl-installer to be able to invoke it to install the packages included in
the qpr file excluding the dev components.

Thanks,

Alain
