If AWK has been installed in a non-standard location, the environment
variable AWK_PATH must be set to specify the location of the executable.
Use this function to set AWK_PATH in your .Renviron file. Most users
should NOT set AWK_PATH, only do so if you have installed AWK in
non-standard location and auk cannot find it. This function first looks

has already been set in .Renviron.
Edits .Renviron, sets AWK_PATH for the current session, then
returns the EBD path invisibly.
