## 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)
##
