1. On prospero, run

   log_collator --example >> log.in

   to generate an example of the specification file in your directory.

2. Edit log.in to pick up the time range and variables that you want.

  3. Run:  log_collator -i log.in -o log.out
     This creates a binary file called "log.out"

4. Convert log.out to ascii using Todd's C program, where you
   specify the number of columns after -c.  Note that the number of
   columns is 1+n, where n is the number of variables you asked for.
   This is because the first column in log.out is always MJD.
     /users/thunter/programs/bin/readlog -i log.out -c 5 -o log.ascii

5. Read log.ascii into Excel, or whatever you want.
