/*
-** A file which is formatted like a maildrop may have a corresponding map
-** file which is an index to the bounds of each message. The first record
-** of such an map is special, it contains:
-**
-** d_id = number of messages in file
-** d_size = version number of map
-** d_start = last message read
-** d_stop = size of file
-**
-** Each record after that contains:
-**
-** d_id = BBoard-ID: of message, or similar info
-** d_size = size of message in ARPA Internet octets (\n == 2 octets)
-** d_start = starting position of message in file
-** d_stop = stopping position of message in file
-**
-** Note that d_start/d_stop do NOT include the message delimiters, so
-** programs using the map can simply fseek to d_start and keep reading
-** until the position is at d_stop.
