"""
Txrep is a human-readable representation of Stellar transactions that functions
like an assembly language for XDR.

This example shows how to convert stellar transaction to human-readable text,
and then convert it back.

See: https://github.com/stellar/stellar-protocol/blob/master/ecosystem/sep-0011.md
