Actually I wasn't terribly serious when you asked that, but, hey, aolserver-errors.pl is *exactly* the kind of thing that Tcl was originally designed to do.
Unlike the creation of 100,000+ lines of Tcl code to form a "thin layer over an RDBMS" which we now call "OpenACS 4.5"!
AFAIK aolserver-errors.pl hasn't changed an iota since it was written. One of our folks fixed the infinite loop bug (search the archives, as I must do soon so I can include it in our OpenACS 4.5 release). You probably won't make the same mistake in Tcl, which after all is cleaner, less obtuse, doesn't come with a puzzle book, etc ...
I guess one must ask: are their Unices out there that come with Perl but not with Tcl? I assume that Solaris is *not* one of them since Tcl was originally developed by Sun.
