// The new assembly support in Solidity makes writing helpers easy.
// Many have complained how complex it is to use `ecrecover`, especially in conjunction
// with the `eth_sign` RPC call. Here is a helper, which makes that a matter of a single call.
//
// Sample input parameters:
// (with v=0)
// "0x47173285a8d7341e5e972fc677286384f802f8ef42a5ec5f03bbfa254cb01fad",

## Features:
## - host's working directory is mounted to random location as the container's working directory
## - uid/gid of the current user are preserved inside the container
## - a host tmp dir will be mounted as /home/user and published as HOME environment variable inside the container
## - all EXPOSED ports will be published (check `docker port $(docker ps -q|head -n1)`).
## - container will be removed on exit
##
## Examples:
