Generating an inheritance graph

The surya inheritance <files..> command is used to generate the contracts inheritance tree in a graphical format. This command takes the list of files to parse and generates a connected graph with contract names and from which other contracts it's inheriting from.

$ surya inheritance contracts/token/ERC20/*.sol | dot -Tpng > erc20-inheritance.png

The preceding command will generate a file named erc20-inheritance.png in the folder; the generated ...
