Re: v3_4_14 ep-elastic

As the latest recrunch used "lrn", ANALDIR=/net/data/9/Analysis/data and
RECRUNCHDIR=/net/data/9/Analysis/recrunch both link to v3_4_14/lrn, the
links were updated on December 27, 2005.

Regards,

   Michael

p.s. please use ANALDIR for the lates lrn version and RECRUNCHDIR for the
latest lrd or lrn version.
