// Description of a host's hardware and software.
// This is used a few places:
// - it's part of the client's state file, client_state.xml
// - it's passed in the reply to the get_host_info GUI RPC
// - it's included in scheduler RPC requests
//
// Other host-specific info is kept in
// TIME_STATS (on/connected/active fractions)
// NET_STATS (average network bandwidths)
