2011-03-20, by wenzelm
pure Timing.timing, without any exception handling;
2011-03-20, by wenzelm
structure Timing: covers former start_timing/end_timing and Output.timeit etc;
2011-03-20, by wenzelm
pervasive cond_timeit;
2011-03-20, by wenzelm
eliminated dead code;
2011-03-20, by wenzelm
parallel preparation of document variants, within separate directories;
2011-03-20, by wenzelm
Present.init/finish/no_document are not thread-safe -- eliminated futile CRITICAL sections;
2011-03-20, by wenzelm
eliminated redundant doc_prefix1;
2011-03-20, by wenzelm
renamed doc_prefix2 to dump_prefix;
2011-03-20, by wenzelm
tuned;
2011-03-20, by wenzelm
