:: While this program offers the UnSet argument to remove  :
::  environment variables that reflect the Hebrew Date, I prefer to  :
::  :
::  SetLocal  :
::  hebrew.btm set  :
::  Do-What-I-Need-To-Do  :
::  EndLocal  :
::  :
::  as this not only removes the environment variables that reflect  :
::  the Hebrew Date, it also removes anything else that I have  :
::  changed in the environment.  :
