+# While I'd love to factor out this with the vesrion in lonprintout,
+# that would either require a data coupling between modules, which I refuse to perpetuate
+# (there's quite enough of that already), or would require the invention of another infrastructure
+# I'm not quite ready to invent (e.g. an ssi_with_retry object).
+#
+# At least the logic that drives this has been pulled out into loncommon.
+
+
+#
+# ssi_with_retries - Does the server side include of a resource.
+# if the ssi call returns an error we'll retry it up to
+# the number of times requested by the caller.
+# If we still have a proble, no text is appended to the
+# output and we set some global variables.
+# to indicate to the caller an SSI error occurred.
+# All of this is supposed to deal with the issues described
+# in LonCAPA BZ 5631 see:
+# http://bugs.lon-capa.org/show_bug.cgi?id=5631
+# by informing the user that this happened.
+#
+# Parameters:
+# resource - The resource to include. This is passed directly, without
+# interpretation to lonnet::ssi.
+# form - The form hash parameters that guide the interpretation of the resource
+#
+# retries - Number of retries allowed before giving up completely.
+# Returns:
+# On success, returns the rendered resource identified by the resource parameter.
+# Side Effects:
+# The following global variables can be set:
+# ssi_error - If an unrecoverable error occurred this becomes true.
+# It is up to the caller to initialize this to false
+# if desired.
+# ssi_error_resource - If an unrecoverable error occurred, this is the value
+# of the resource that could not be rendered by the ssi
+# call.
+# ssi_error_message - The error string fetched from the ssi response
+# in the event of an error.
