  To configure Xymon, the following options are available:
     --pcreinclude DIRECTORY  : Specify location of PCRE include files
     --pcrelib DIRECTORY      : Specify location of PCRE libraries
     --make /path/to/gnumake  : Specify location of the GNU make program

  The script will search a number of standard directories for
  all of these files, so you normally do not have to specify any options.
