Well, my script is actually a PAR::Packer's pp generated exe file, installed with a shortcut icon in some operators' desktops. It collects some logs left by other running systems according to some manual schedules, cross all that info, generates a report in HTML format, and saves it in a shared file repository. The number of times it runs every day, depends on the weekday. As the reports must be kept, different names are used (adding the timestamp for example).
Every night, one of the sysops has to check how the thing is going, and the fastest and simplest way for them is to double-click that icon and wait for the report to be displayed (instead of searching the repository for it as a second step).
Don't say it loud, but perl is not (officially) allowed in our systems, so we are hiding our scripts with PAR ;-)
