Running `optimin` is the same as running `afl-cmin`:
```
-Required parameters:
- -i dir - input directory with starting corpus
- -o dir - output directory for minimized files
-
-Execution control settings:
- -f file - location read by the fuzzed program (stdin)
- -m megs - memory limit for child process (none MB)
- -t msec - run time limit for child process (none)
- -O - use binary-only instrumentation (FRIDA mode)
- -Q - use binary-only instrumentation (QEMU mode)
- -U - use unicorn-based instrumentation (unicorn mode)
-
-Minimization settings:
- -C - keep crashing inputs, reject everything else
- -e - solve for edge coverage only, ignore hit counts
-
-For additional tips, please consult README.md
-
-Environment variables used:
-AFL_ALLOW_TMP: allow unsafe use of input/output directories under {/var}/tmp
-AFL_CRASH_EXITCODE: optional child exit code to be interpreted as crash
-AFL_FORKSRV_INIT_TMOUT: time the fuzzer waits for the forkserver to come up
-AFL_KEEP_TRACES: leave the temporary <out_dir>/.traces directory
-AFL_KILL_SIGNAL: Signal delivered to child processes on timeout (default: SIGKILL)
-AFL_NO_FORKSRV: run target via execve instead of using the forkserver
-AFL_PATH: path for the afl-showmap binary if not found anywhere in PATH
-AFL_PRINT_FILENAMES: If set, the filename currently processed will be printed to stdout
-AFL_SKIP_BIN_CHECK: skip afl instrumentation checks for target binary
