/* The function check_wfdb.c determines which version of the WFDB
   software package is currently installed and returns a flag to
   standard output depending on the command line argument.  The
   following scenarios may occur:

   1) If the argument install has been included at the command line
      and a version less than or equal to 10.1.6 is currently installed, 
      the flag will be set to 1.
   2) If the argument install has been included at the command line
      and a version greater than 10.1.6 is currently installed, the 
      flag will be set to 0.
   3) If the argument uninstall been included at the command line
      and a version equal to 10.1.6 is currently installed, the flag
      will be set to 1.
   4) If the argument uninstall has been included at the command line
      and a version not equal to 10.1.6 is currently installed, the flag
      will be set to 0.

   Function argument: either install or uninstall

   Function outputs: (none)
