+Tag name:  release-cesm2.0.01
+Originator(s): erik/jedwards4b
+Date: Oct 09, 2018
+One-line Summary:  New r8th routing file, pylint and py3 checking, fill value needed for pio2
+
+Add in 8th degree routine file. Run pylint and check for py3 compatability.
+There's explict setting of fill type. And also explicit use of shr_kind_r4 for 
+kind rather than real(4), which is a better mechanism. Also ncd_getiodesc 
+will read in PIO_DOUBLE for input xtype= PIO_DOUBLE or PIO_REAL. Most of this
+is direct from jedwards4b (other than r8th addition).
+
+MOSART Master Tag This Corresponds To: Identical to mosart1_0_31
+
+Science  changes since: release-cesm2.0.00
+   Added in 8th degree routing file (r8th)
+Software changes since: release-cesm2.0.00
+   Run pylint on python buildlib and buildnml scripts, check for py3 compatibility.
+   Corrects the integer fill value. Needed for pio2.
