+# install_ca_certs.sh -- copy the specified CA certificates into this source so that they can be used
+#                        to build the software via docker.

+#   where CA_CERT_FILE is a file path to a CA certificate to install
+#
+# This script helps address the problem with docker-based builds when run within a firewall that
+# replaces external site certificates with ones signed by a non-standard CA, causing the retrieval
+# of software dependencies to fail.  This script is used by oar-docker's localbuild script to receive 
+# extra CA certificates that addresses such failures.  Because localdeploy makes no assumptions about 
+# how this source code repository builds using docker, this script encapsulates that knowledge on 
+# behalf of localbuild.
+#
+# Note: if this repository does not require/support use of non-standard CA certificates, remove (or
+# rename) this script.
