+VERSION file is used to test appendability of tar as well as to mark

+is checked and its status as a valid tar file is validated. This was
+done using a new function ~checkMakeTar~.

+** TODO Rewrite buffer loop to reduce lag between gpspipe runs
+2020-07-03T17:10Z; bktei> As is, there is still a 5-6 second lag
+between when ~gpspipe~ times out at the end of a buffer round and when
+~gpspipe~ is called by the subsequent buffer round. I believe this can
+be reduced by moving variable manipulations inside the
+asynchronously-executed magicWriteBuffer() function. Ideally, the
+while loop should look like:
+
+#+BEGIN_EXAMPLE
+while( $SECONDS < $SCRIPT_TTL); do
+    gpspipe-r > "$DIR_TMP"/buffer.nmea
+    writeBuffer &
+done
+#+END_EXAMPLE
