// The following can be used to select desired outputs based
// on file and contract names.
// If this field is omitted, then the compiler loads and does type checking,
// but will not generate any outputs apart from errors.
// The first level key is the file name and the second level key is the contract name.
// An empty contract name is used for outputs that are not tied to a contract
// but to the whole source file like the AST.
// A star as contract name refers to all contracts in the file.
// Similarly, a star as a file name matches all files.
// To select all outputs the compiler can possibly generate, use
// "outputSelection: { "": { "": [ "" ], "": [ "" ] } }"
// but note that this might slow down the compilation process needlessly.
//
// The available output types are as follows:
//
// File level (needs empty string as contract name):
// ast - AST of all source files
// legacyAST - legacy AST of all source files
//
// Contract level (needs the contract name or ""):
// abi - ABI
// devdoc - Developer documentation (natspec)
// userdoc - User documentation (natspec)
// metadata - Metadata
// ir - Yul intermediate representation of the code before optimization
// irOptimized - Intermediate representation after optimization
// evm.assembly - New assembly format
// evm.legacyAssembly - Old-style assembly format in JSON
// evm.bytecode.object - Bytecode object
// evm.bytecode.opcodes - Opcodes list
// evm.bytecode.sourceMap - Source mapping (useful for debugging)
// evm.bytecode.linkReferences - Link references (if unlinked object)
// evm.deployedBytecode - Deployed bytecode (has the same options as evm.bytecode)
// evm.methodIdentifiers - The list of function hashes
// evm.gasEstimates - Function gas estimates
// ewasm.wast - eWASM S-expressions format (not supported at the moment)
// ewasm.wasm - eWASM binary format (not supported at the moment)
//
// Note that using a using evm, evm.bytecode, ewasm, etc. will select every
// target part of that output. Additionally, * can be used as a wildcard to request everything.
