+Generate a Python blockchain test from a transaction hash.
+
+This script can be used to generate Python source for a blockchain test case
+that replays a mainnet or testnet transaction from its transaction hash.
+
+Requirements:
+
+1. Access to an archive node for the network where the transaction
+    originates. A provider may be used.
+2. The transaction hash of a type 0 transaction (currently only legacy
+    transactions are supported).
+
+Example Usage:
+
+1. Generate a test for a transaction with hash
+
+    ```console
+    uv run gentest \
+    0xa41f343be7a150b740e5c939fa4d89f3a2850dbe21715df96b612fc20d1906be \
+    tests/paris/test_0xa41f.py
+    ```
+
+2. Fill the test:
+
+    ```console
+    fill --fork=Paris tests/paris/test_0xa41f.py
+    ```
+
+Limitations:
+
+1. Only legacy transaction types (type 0) are currently supported.
