+  JAVA_OPTS     environment variable  # default: "-Dfile.encoding=UTF8"
+  SBT_OPTS      environment variable  # default: "-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=512m -Xmx2g -Xss2m"
+  -Dkey=val     pass -Dkey=val directly to the jvm

+corresponding variable is unset. In the case of a duplicated option,
+SBT_OPTS takes precedence over JAVA_OPTS, and command line options
+take precedence over both.
