@ -10,17 +10,18 @@ This is a hecking fuzzer. It does the thing.
## Usage
```
usage: python -m gazprea_fuzzer.py [-h] [-b SIZE] [--seed SEED] <config_file>
usage: gazprea_fuzzer.py [-h] [-b BATCH] [--seed SEED] config_file
Procedurally generate a test case for Gazprea
positional arguments:
config path to your configuration file
name name of the test case to generate (name.in, name.ins, name.out)
config_file path to your configuration file
optional arguments:
-h, --help show the help message and exit
-b, --batch SIZE generate SIZE cases (fuzzer/input/nameX.in, /instream/..., /outputs/...)
options:
-h, --help show this help message and exit
-b BATCH, --batch BATCH
generate SIZE cases (fuzzer/input/nameX.in,
/instream/..., /outputs/...)
--seed SEED rng seed
