 For a friendlier display, you could pipe the output of the serializer to a file and use a visual tool like [Meld](http://meldmerge.org/) that shows intra-line differences:
 
 ```bash
-$ cat test-cases/tx1.json | sed -e 's/"Fee": "10"/"Fee": "100"/' | node index.js --stdin --stdin > /tmp/tx1-modified.txt && meld /tmp/tx1-modified.txt test-cases/tx1-binary.txt
