## Provision of `eth` and `snap` protocol version parameters
##
## `Eth` related parameters:
## `ethVersions`: seq[int] -- constant list of all available versions
## `eth` -- type symbol of default version
## `proto_eth` -- export of default version directives
##
## `Snap` related parameters:
## `snap` -- type symbol of default version
## `proto_snap` -- export of default version directives
## ..aliases.. -- type names, syntactic sugar (see below)
##
