I haven't used tcl before and just need to do one trick, I can do it trivially in something like bash but I need it to work cross-platform (e.g. tcl in cygwin on windows).
Can someone suggest a short (5-10) obfuscated function that just returns 0 after taking two string args? It just can't do something like run shell commands that won't work under Mac/Cygwin.
fwiw, why do this: buying some time in writing a test- the thing generating one of the files is broken but I can't change it, making a hack in the TCL test script until I make extensive changes to use a different 'test core' that isn't broken. For now just declare the first file as 'good' if it exists.
