-/**
- * Represents a static hosts file which maps hostnames to IPs
- *
- * Hosts files are used on most systems to avoid actually hitting the DNS for
- * certain common hostnames.
- *
- * Most notably, this file usually contains an entry to map "localhost" to the
- * local IP. Windows is a notable exception here, as Windows does not actually
- * include "localhost" in this file by default. To compensate for this, this
- * class may explicitly be wrapped in another HostsFile instance which
- * hard-codes these entries for Windows (see also Factory).
- *
- * This class mostly exists to abstract the parsing/extraction process so this
- * can be replaced with a faster alternative in the future.
