I would like to add something which we had to learn the hard way when working 
on a platform-independent project with a commandline-interface: the native 
commandline in MS Windows (cmd.exe) can only digest input with significantly 
fewer characters than the usual shells in Linux and Solaris - and then you get 
really strange and unhelpful error messages. The number of characters for 
Windows XP is 8191 characters, for older systems (Windows 2000) it is about 
2000 characters. This was a showstopper-class problem for us (we worked around 
this by putting all previous commandline arguments into an optional parameter 
file), much later we found an official Microsoft article on this:
