Also, please read 'perldoc -f close'.  It is just as important to check
the return value of close, if the filehandle in question was written to.

       close   Closes the file or pipe associated with the file
               handle, returning true only if stdio successfully
               flushes buffers and closes the system file
               descriptor.  

Have fun,
-C.
