+#!/bin/sh
+# vim: set ts=4:
+#
+# This jruby start script is rewrite of (poor) upstream's jruby.bash.
+# It's POSIX compatible, more clean, with sensible defaults for Alpine Linux
+# and without Windows, OS X and Truffle stuff. Beside that it should support
+# all the options of jruby.bash (hopefully) with the same behaviour.
+#
+# -----BEGIN HELP-----
+#
+# Environment variables:
+#     CLASSPATH      Additional paths to be added to the end of the Java classpath.
+#                    This may be overwritten by CLI argument -J-classpath or -J-cp.
+#     JAVA_HOME      Path to directory where is JRE/JVM installed to use specific java/jdb binary,
+#                    not the one on the PATH.
+#     JAVA_OPTS      Default options to be passed to JVM.
+#     JRUBY_HOME     Path to directory where JRuby is installed (default is /usr/share/java/jruby).
+#     JRUBY_OPTS     Default JRuby command line arguments.
+#     JRUBY_SHELL    Path to the system shell executable (default is /bin/sh).
+#     PROFILE_ARGS   Arguments for the instrumented profiler.
+#
+# Deprecated environment variables (for compatibility):
+#     JAVA_MEM       The -Xmx (maximum memory allocation) parameter for JVM (e.g. -Xmx128M).
+#                    This may be overwritten by CLI argument -J-Xmx.
+#     JAVA_STACK     The -Xss (stack size) parameter for JVM (default is -Xss2048k).
+#                    This may be overwritten by CLI argument -J-Xss.
+#     JAVA_VM        What JIT mode to use; -client, or -server (default is -server).
+#                    This may be overwritten by CLI arguments --server, --client, and --dev.
+#     JRUBY_PARENT_CLASSPATH  Classpath propagated from the parent JRuby process.
+#
+# All the environment variables are optional.
