From a3dd9d10f39bddfb386370eb01e76cbbb0fe6fbb Mon Sep 17 00:00:00 2001 From: warptangent Date: Tue, 3 Mar 2015 17:20:27 -0800 Subject: [PATCH] blockchain_converter: Add support for batch transactions Add log level support. Add testnet support. Add command-line options: --help --data-dir --testnet-data-dir --testnet --log-level --batch --batch-size --block-number See help for usage.
