I have improved the documentation:

Adjust the tasks.sieve.qmin parameter accordingly to prevent
already-sieved special-q ranges from being sieved again. To do that:

* go into the cxx.upload directory
* list the cxx.sieving.xxx-yyy.*.gz files
* find the largest yyy value, and use it as new qmin

tasks.sieve.sieving.qmin seems to work, but tasks.sieve.qmin is simpler indeed.

thank you for the feedback,
