That's one in the eye for the Sun parsers. I'm glad you found it, I was drawing a blank
It is a bit typical though. I remember a number of years ago I was doing maintenance stuff on a system where the config files were ultra-fussy. I mean, if a tab happened to be spaces, or a space was in the wrong place, it would all fall over in a heap. It was horribly strict and problems would take many hours to root out.
In fact, now I come to think about it, 'make' is painfully fussy and I use that semi-regularly. And that's a standard tool.
