+# The epics-containers IOC startup script.
+#
+# This script is used to start an EPICS IOC in a Kubernetes pod. Implementers
+# of generic IOCs are free to replace this script with their own. But
+# this script as is should work for most IOCs.
+#
+# When a generic IOC runs in a kubernetes pod it is expected to have
+# a config folder that defines the IOC instance.
+# The helm chart for the generic IOC will mount the config folder
+# as a configMap and this turns a generic IOC into aspecific IOC instance.
+#
+# Here we support the following set of options for the contents of
+# the config folder:
+#
+# 1. start.sh ******************************************************************
+#    If the config folder contains a start.sh script it will be executed.
+#    This allows the instance implementer to provide a conmpletely custom
+#    startup script.
+#
+# 2. ioc.yaml *************************************************************
+#    If the config folder contains an ioc.yaml file we invoke the ibek tool to
+#    generate the startup script and database. Then launch with the generated
+#    startup script.
+#
+# 3. st.cmd + ioc.subst *********************************************************
+#    If the config folder contains a st.cmd script and a ioc.subst file then
+#    optionally generate ioc.db from the ioc.subst file and use the st.cmd script
+#    as the IOC startup script. Note that the expanded database file will
+#    be generated in /tmp/ioc.db
+#
+# 4. empty config folder *******************************************************
+#    If the config folder is empty then this IOC will launch the example in
+#    ./example folder
+#
+# RTEMS IOCS - RTEMS IOC startup files can be generated using 2,3,4 above. For
+# RTEMS we do not execute the ioc inside of the pod. Instead we:
+#  - copy the IOC directory to the RTEMS mount point
+#  - send a reboot command to the RTEMS crate
+#  - start a telnet session to the RTEMS IOC console
