NAME
     rst2rcyc - Copy GEOS-4/5 restarts from permanent storage to recycle
          
SYNOPSIS

     rst2rcyc [...options...]  nymd  nhms  expid  
          
DESCRIPTION

     The following parameter are required 

     nymd     Year-month-day, e.g., 19990901  for 01 Sept 1999 
     nhms     Hour-minutes-seconds, e.g., 120000
     expid    Experiment name

OPTIONS
 
 -h            prints this usage notice

 -mst          directory path name where original restarts are stored,
               e.g., /output/todling/f5b2_d1/rs/Y2004/M07; 
                  default: /output/user/expid/rs/Yyyyy/Mmm

 -scr          directory path where restarts are to be copied to with
               naming convention for initializing DAS/GCM, e.g.,
               /scratch1/todling/f5b2_d1/recycle;
                  default: /scratch1/user/expid/recycle
