A "seed" command has been added. This is not intended for human use
but as a way for game logs to set the PRNG (pseudorandom-number generator) so
that random events (dwarf & pirate appearances, the bird's magic word)
will be reproducible.
+A "version" command has beem added. This has no effect on gameplay.
+The text displayed by the "news" command has been updated.

A -l command-line option has been added. When this is given (with a
file path argument) each command entered will be logged to the
specified file. Additionally, a generated "seed" command will be put
that was performed because the FORTRAN it was written in had no string
type. Text from the adventure.text file was compiled into sequences
of sixbit code points in a restricted character set, packed 5 to a

verb was one of these words, and what would be string operations in a
more recent language were all done on sequences of these words.

languages easier.

* Linked lists (for objects at a location) are implemented using an array
of link indices. This is a surviving FORTRANism that is quite unlike
normal practice in C or any more modern language. We have not tried
arrays are a cell larger than they strictly need to be and cell 0 is
unused.

to introduce semantic types.
