sand_align_master  is  the second step in the SAND assembler.  It reads in a list of sequences and a list
       of candidate pairs to consider,  generated  by  sand_filter_master(1).   It  then  performs  all  of  the
       comparisons and produces a list of overlaps (in OVL format) that exceed a quality threshhold.

       This  program  uses  the  Work  Queue  system  to  distributed  tasks  among  processors.  After starting
       sand_align_master, you must start a number of work_queue_worker(1) processes  on  remote  machines.   The
       workers  will  then  connect back to the master process and begin executing tasks.  The actual alignments
       are performed by sand_align_kernel(1) on each machine.

       Suppose that you begin with  a  compressed  FASTA  file  (mydata.cfa)  and  a  list  of  candidate  reads
       (mydata.cand)  generated by sand_filter_master(1).  First, start a single work_queue_worker(1) process in
       the background.  Then, invoke sand_align_master() as follows:

               % work_queue_worker localhost 9123 &
               % sand_align_master sand_align_kernel mydata.cand mydata.cfa mydata.ovl

       To speed up the process, run more work_queue_worker() processes on other  machines,  or  use  condor_sub‐mit_workers(1) or uge_submit_workers(1) to start hundreds of workers in your local batch system.

       On success, returns zero.  On failure, returns non-zero.
