manage_eos
This tool is intended to make it easier to configure and bootstrap an eosio blockchain.
It is recommended to use zrts/run_eos so that the "eosc" command used in the script will be properly interpreted.
You should also configure a wallet and optionally you can store its password (assuming this is a local test network) in the file defined by the variable ${WALLET_PASSWORD}, so that it gets unlocked automatically.
Proceed to launching your nodeos with a clean state and running eos_init_chain.
After that you can use eos_init_contract contract_name to easily build and deploy the contract inside ~/git/contract_name.
Make sure you also customize both functions and the keys file to your needs.
