[jdom-interest] Build error in jdom-contrib

[Randall Parker]

Alex,

The single ampersand is a command separator for multiple commands on a line. The double ampersand is also but 
it will only execute what is on the right of it if the program on the left of it returns a 0. In the example below it will n 
ot run the java process if it fails to find the directory to cd into.

As for Win9x vs NT: I know NT supports both of them. I am pretty sure that Win9x supports the single ampersand. 
But Win9x might not support the double ampersand. Not sure. Win9x does have a less able command interpreter. I 
can't find any doc on this so I'm not sure.

I also wonder whether Win9x might have some command line length limit that is less less than NT's. 

Oh, the cmd: Isn't it command.com in Win9x? Not cmd.exe?
