\#
\#   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 shells will NOT work, because this script
\#       requires all of these POSIX shell features:
\#         * functions;
\#         * expansions «#[[\$]]#var», «#[[\$]]#{var}», «#[[\$]]#{var:-default}», «#[[\$]]#{var+SET}»,
\#           «#[[\$]]#{var\#prefix}», «#[[\$]]#{var%suffix}», and «#[[\$]]#( cmd )»;
\#         * compound commands having a testable exit status, especially «case»;
\#         * various built-in commands including «command», «set», and «ulimit».
\#
\#   Important for patching:
\#
\#   (2) This script targets any POSIX shell, so it avoids extensions provided
\#       by Bash, Ksh, etc; in particular arrays are avoided.
\#
\#       The "traditional" practice of packing multiple parameters into a
\#       space-separated string is a well documented source of bugs and security
\#       problems, so this is (mostly) avoided, by progressively accumulating
\#       options in "#[[\$]]#@", and eventually passing that to Java.
\#
\#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
\#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
\#       see the in-line comments for details.
\#
\#       There are tweaks for specific operating systems such as AIX, CygWin,
\#       Darwin, MinGW, and NonStop.
\#
\#   (3) This script is generated from the Groovy template
\#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
\#       within the Gradle project.

\#
\# but POSIX shell has neither arrays nor command substitution, so instead we
\# post-process each arg (as a line of input to sed) to backslash-escape any
\# character that might be a shell metacharacter, then use eval to reverse
\# that process (while maintaining the separation between arguments), and wrap
\# the whole thing up as a single "set" statement.
\#
\# This will of course break if any of these variables contains a newline or
\# an unmatched quote.
