# 2007-10-13 | nj6n  | Script creation  (v1.0)
# 2007-10-14 | nj6n  | Added javAPRS configuation commands and decho installation (v1.1)
# 2007-10-16 | nj6n  | Added check for gateway conf files.  Validated Range parameter;
#                      nothing entered = 0 range, Removed numRptrs (not needed), added
#                      update to CtrlrIP= parameter - set to ZR_ADDR parameter value.
#                      Added query and setting for controller port number per Pete AE5PL.
# 2007-11-22 | nj6n  | Install dplus instead of decho now.
