+#
+# Execute acommand with args, in such a way that
+# both stdout and stderr from acommand are appended to
+# theloggfile.
+#
+# Preserve stdout and stderr, so that the stdout
+# from logger.sh is the same from acommand and equally
+# for stderr.
+#
+# Propagate the result code from acommand so that
+# ./logger.sh exits with the same result code.
+
+# Create a temporary directory to store the result code from
+# the wrapped command.
