Re: ZIP archives

Be advised that if the option to install the BSD subsystem was 
unchecked during OS X installation, this will not be available. This 
bit me early on with one of my own applications and I had to do some 
digging to figure out that this was the problem. The user had 
reinstalled her OS and for whatever reason (I think she said to "save 
space" on her laptop) chose not to install the BSD subsystem. This 
had come up several times within a three month period before I 
finally patched it (lazy, I know), so it's definitely frequent enough 
to look out for.

  Check for the presence of this tool before attempting to use it; 
don't rely on it being there. :-)
