REM This script tries to find the Larceny binaries and to select the correct
REM pair.  If LARCENY_ROOT is set, it looks there; otherwise, if the directory
REM this script is in is named Scripts, it looks in the parent; otherwise, it
REM looks in the same directory as itself.

REM The setlocal command makes any changes to environment variables local to
REM this script.  This keeps changes to the LARCENY_ROOT environment variable
REM from persisting across invocations of this script.
