Test Plan:

1. First try to leave off the --dir option from an rhn-satellite-exporter
command. It should give you an error that looks like this: --dir not included!

      rhn-satellite-exporter -crhel-i386-as-4

2. Next try using a directory that doesn't exist with the --dir option. You
should get this error: can't access output directory

      rhn-satellite-exporter --dir=foo -crhel-i386-as-4

3. Next try performing a correct export. All of the data should show up in the
directory you specify and not in some weird location.

      rhn-satellite-exporter --dir=test1

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


[root@rlx-3-14 ~]# rhn-satellite-exporter --channel=rhel-i386-as-4 --dir=myexports

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.
