I create a new method for the rpm module.
*With glob integration
The method for the rpm module is done, thanks for the suggestions given
during all of the work.
The code is available at: http://func.pastebin.com/f75c77458 and I also
am sending the diff and git file in annex.

In a conjunct effort me and Varinder Singh merged the RPM Module
with the Yum Module and we create a module called Packages.
The module is available at:

Don't call it packages.
unless the plan is to merge in deb package and other support as well.

Further -- joining the install and remove code with the yum code won't
work on RHEL 4 installations, since it would require yum to be installed.
We also can't be changing API signatures for modules like this
midstream, so this introduces duplication.
If you want to create a higher level packages module (that uses the
rpm and yum module code), this is reasonable... but as Seth says, it
should also support (at minimum) Debian and be an abstract
concept. It should also reuse the code from the other two modules.
That's a great idea, I want to upstream this method to the rpm module
than I can begin to work in create the higher level "Packages module".
In the time I was thinking in merge the rpm module with the yum module
I didn't think that other people could have been using scripts who uses
code from these modules as they are right now. Keeping the rpm and the
yum module and creating a super module that call these modules is
probably the best way to go, thanks again for the comments.
PackageKit sort of comes up as a logical abstraction layer, but I
think that's a bad idea seeing that's not available for EL 4, and
enterprise-ness is the primary install base.
