@echo off
:: Nohup-like utility for windows written with zero dependencies on non-standard code.
::
:: Usage forget process_name fullpath arguments
::
:: Ex. forget tomcat c:\apps\tomcat start
::
:: Uses the schtasks command to launch whatever the command is in the next minute.
:: If the process is already running, it is shutdown first.
::
:: Author Adrian Cole
