marvin, regarding comment #30:

1)
>"assuming you only need the log files."

Unfortunately, this isn't the case.

2) Regarding attachments, the article requested separate attachments for
each command (not combined into one). This is to help developers know
what it is they are looking at, versus guessing at what was attached,
trying to deduce if something was missed, or figure out why something
unexpected happen.
