[Spacewalk-list] Pull rhn errata into spacewalk

[Evan Frey]

This script is another attempt at pulling RHN errata into spacewalk.  I 
have used the other out there and found that they didn't do what I 
wanted.  My hit list was as follows:

  - From http://lists.centos.org/pipermail/centos-announce pull the 
monthly digest down to pull out all of the advisory numbers
  - Log into RHN and use the xmlrpc api to pull the details of each 
erratum
  - Push the erratum into spacewalk using the xmlrpc api.  This should 
be pushed dynamically rather then needing a configuration file


The items that I feel are still outstanding and plan to work on:

  - Currently the script publishs the errata to all channels.  The next 
iteration should publish only to channels where the rpm file exists.
  - The script does not check if erratum is already published, it just 
makes the attempt to publish it again (it will silently fail if the 
erratum is already there uploaded).  Not sure what the speed gain will 
be checking for errata on the local spacewalk server as opposed to just 
trying to publish, if it is negligible this will not be addressed.
  - Keywords are currently just the list of packages.  This will change 
to be the keywords from RHN.
  - Multithread the app.  Not sure I really care about this, but someone 
brought it up so I may look into it.


The project is hosted on sourceforge at 
http://rhn2spacewalk.sourceforge.net/

It requires:

perl-Frontier-RPC
perl-List-MoreUtils

Additionally I used perl-5.8.8-32 so it had the following built in:

Getopt::Long
Switch
