@ -63,7 +63,6 @@ The most important flags are::
timeout 1200 Timeout in seconds (if positive). If one unit runs more than this number of seconds the process will abort.
max_total_time 0 If positive, indicates the maximal total time in seconds to run the fuzzer.
help 0 Print help.
save_minimized_corpus 0 If 1, the minimized corpus is saved into the first input directory. Example: ./fuzzer -save_minimized_corpus=1 NEW_EMPTY_DIR OLD_CORPUS
merge 0 If 1, the 2-nd, 3-rd, etc corpora will be merged into the 1-st corpus. Only interesting units will be taken.
jobs 0 Number of jobs to run. If jobs >= 1 we spawn this number of jobs in separate worker processes with stdout/stderr redirected to fuzz-JOB.log.
workers 0 Number of simultaneous worker processes to run the jobs. If zero, "min(jobs,NumberOfCpuCores()/2)" is used.
