+# Sets GEM_HOME/GEM_PATH in the environment BEFORE jruby boots, because
+# mutating those variables inside a running JRuby process does not reliably
+# affect gem resolution (JRuby issue #5269). Setting them pre-boot lets
+# RubyGems pick them up natively. Self-locating, so the whole tree can be
+# relocated without editing anything.
+#
+# Usage:  ./run_radio.sh <script.rb> [args...]
+#   e.g.  ./run_radio.sh fetch_podcasts.rb --list-shows
