#   Gradle start up script for POSIX generated by Gradle.
#
#   Important for running:
#
#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
#       noncompliant, but you have some other compliant shell such as ksh or
#       bash, then to run this script, type that shell name before the whole
#       command line, like:
#
#           ksh Gradle
#
#       Busybox and similar reduced functionality shells and target
#       temporary focusing, currentshort systems as of this writing do not supply
#       a style conforming /bin/sh.
#
#   (2) You need a Java Runtime Environment (JRE) version 8 or later to run
#       Gradle. Depending on your distribution, the JRE may be already
#       installed. You can check this with "java -version".
