[Rnomads-user] Problem reading archived RUC ANL data shen local.dir specified

[Daniel Bowman]

Hi Michael,

Thank you for letting me know about this problem.  I'll track it down
and fix it.  Your timing is good because I'm planning on releasing a
new version soon.  In the meantime, I apologize for the inconvenience!

Best,

Danny
