As Jan pointed out, the patch does not apply.

I am assuming that, if you are asking for opinions, then you are
volunteering to fix the ARI scripts :-). Here are my opinions. Thanks
a lot for doing this!

Is this script called in some cronjob, or is it intended to be called
directly by the user? I don't see it being called anywhere in the
sources. If it is called from a cronjob, then maybe it's worth
providing an example of a simple crontab script which would work for
this purpose.

Also, if it is supposed to be called by the user, then I think it should
accept command line arguments.

Is this a new script? If not, I believe the copyright notice should
include the previous years of existence.

Since we are now putting the scripts in the main tree, which IMO is an
incentive for everyone to run them and check the results, I believe we
cannot always assume that certain programs are available at the user's
machine. For this reason, maybe it's good to check if the executables
(like `dirname') being used in these sources actually exist?

What do you think of creating a new file which would contain this giant
awk script? I see there are many "sections" in this script, so maybe we
could even separate those script into logical files and use multiple `-f
FILE' arguments to awk. But I guess only putting this huge script into
a separate file is enough for now...

Thanks,
