-// contract tracking versions added by designated signers.
-// designed to track versions of geth (go-ethereum) recommended by the
-// go-ethereum team. geth client interfaces with contract through ABI by simply
-// reading the full state and then deciding on recommended version based on
-// some logic (e.g. version date & number of signers).
-//
-// to keep things simple, the contract does not use FSM for multisig
-// but rather allows any designated signer to add a version or vote for an
-// existing version. this avoids need to track voting-in-progress states and
-// also provides history of all past versions.
