These commands aren't portable to all Unix platforms.  Some older 
versions of Unix don't know about `mkdir -p', and the `z' modifier is 
only supported by GNU `tar'.  Of course, on Linux everything but the 
kernel is from GNU, but at least a comment in the shell script should 
mention potential portability problems.  A better way would be to replace 
`mkdir -p' by a shell loop that does the same (`mkinstalldirs' script in 
every GNU source distribution does that) and use "gzip -d -c | tar xvf -" 
pipe to unzip .tar.gz files.
