Currently, wikiproject_scripts relies on qsub error logging, where stack traces are dumped to an .err file. This reporting is useful, but I do not know when it happens, and so these errors happen repeatedly until I somehow notice. (Qsub's built in email reporting system does not provide enough information; it reports an exit code, but not the content of stderr.)
It would be better to have a more proactive error reporting method so that I can act more quickly to resolve problems. In particular, I would like to be emailed whenever a script fails.
