"HawkEye -h" command does not list the -params option

[leavesntwigs]

-params option points HawkEye to the location of a parameter file. This option is printed with this command

~/lrose/bin/HawkEye -params

It would be nice to have the -params option presented when the -h (help) option is presented to HawkEye.
