Test Plan:

1. Try exporting stuff without including either -c or --channel. You should get
a an error like this: --channel not included!

      rhn-satellite-exporter --dir=test3

2. Try exporting a non-existant channel. You should get a message that looks
like this: 11:55:11 Error: Channel foo not found.

      rhn-satellite-exporter --dir=test3 -cfoo

3. Try exporting a channel for real this time. After it is exported verify that
the channel you said to export is actually the channel that was exported. You
can do that by cd'ing into the channels directory in the export directory and
making sure it contains a directory for the channel that you exported.
Additionally, you can open up the channel.xml file in that directory and verify
that the 'label' attribute of the rhn-channel tag points to the correct channel.

      rhn-satellite-exporter --dir=test3 -crhn-tools

4. Try exporting more than one channel. After they have been exported, verify
that the channels you said to export are actually the channels that were
exported. You can do that by cd'ing into the channels directory in the export
directory and making sure it contains directories for both of the channels that
you exported. Additionally, you can open up the channel.xml file in both of
those directories and verify that the 'label' attribute of the rhn-channel tag
points to the correct channels.

The tool is broken.  Please see the two tracebacks below:

ISO: rhn-satellite-4.0.5-2-redhat-linux-as-i386-4-embedded-oracle.iso

The reason it failed was because I missed a file in the Makefile and spec file.
string_buffer.py has been added and the rhns packages rebuilt. The changes are
in the 4.0.5-28 or later rhns-satellite-tools package.

Looks good on QA

Released.
