Tinman
I'd like to suggest that we consider bringing in tinman to gitlab:
https://github.com/steemit/tinman
In a nutshell, this is a python tool that allows blockchain devs to deploy a testnet. It allows devs to create a testnet by copying the accounts and creating them on the testnet, along with their keys.
It also allows devs to run a smaller testnet containing about 2,000, if they find this convenient. I would be happy to maintain this repo, once it is brought over to this gitlab.
