- * High level parsing of addresses:
- *
- * The routines in sbr/mf.c parse the syntactic representations of
- * addresses. The routines in sbr/addrsbr.c associate semantics with those
- * addresses.
- *
- * If #ifdef DUMB is in effect, a full 822-style parser is called
- * for syntax recongition. This breaks each address into its components.
- * Note however that no semantics are assumed about the parts or their
- * totality. This means that implicit hostnames aren't made explicit,
- * and explicit hostnames aren't expanded to their "official" represenations.
- *
- * If DUMB is not in effect, then this module does some
- * high-level thinking about what the addresses are.
- *
- * 1. for MMDF systems:
- *
- * string%<uucp>@<local> -> string
- *
- * 2. for non-MMDF systems:
- *
- * string@host.<uucp> -> host!string
- *
- * 3. for any system, an address interpreted relative to the local host:
- *
- * string@<uucp> -> string
- *
- * For cases (1) and (3) above, the leftmost host is extracted. If it's not
- * present, the local host is used. If the tests above fail, the address is
- * considered to be a real 822-style address.
- *
- * If an explicit host is not present, then MH checks for a bang to indicate
- * an explicit UUCP-style address. If so, this is noted. If not, the host is
- * defaulted, typically to the local host. The lack of an explict host is
- * also noted.
- *
- * If an explicit 822-style host is present, then MH checks to see if it
- * can expand this to the official name for the host. If the hostname is
- * unknown, the address is so typed.
- *
- * To summarize, when we're all done, here's what MH knows about the address:
- *
- * DUMB - type: local, uucp, or network
- * host: not locally defaulted, not explicitly expanded
- * everything else
- *
- * other - type: local, uucp, network, unknown
- * everything else
