+"""Creates a directory containing seed inputs from a json file having
+   the following structure:
+   [
+     {
+       "hex": "a901a1182a182a02a3626964781a6d616b655f6261645f7...",

+       "description": "make credential parameters"
+     },
+     ...
+   ]
+
+  Usage:
+    - pass the resulting corpus directory path as the first argument
+    - pass the json file path to make the corpus from as the second argument
+  Example:
+    python make_corpus.py ./corpus ./corpus_file.json
