Hello Pablo,

you can keep the log, tuc and pdf file of every run with the --keeplog, 
--keeptuc and --keeppdf options (type "context --help --expert" to know 
about the file naming).

A new run is started unless:

- the maxruns number of runs has been reached

- the tuc file is identical to the one of the previous run
