18		Tag: blume-20030926-ppautoload
19		Description:
20
21		I modified the read-eval-print loop so that the autoloader gets
22		invoked whenever the prettyprinter tries to look up a symbol that
23		is not currently defined in the toplevel environment but which
24		appears in CM's autoload registry.  As a result, we see far fewer of
25		those ?.Foo.Bar.xxx names in the prettyprinter's output.
26
27		In addition to this I tried to clean up some pieces of the Basis
28		implementation (e.g., Socket, Word8Array) in order to prevent other
29		instances of these ?.Foo.Bar.xxx names from being printed.
30
31		The mechanism that picks names for types still needs some work, though.
32		(Right now it seems that if there is a type A.t which is defined to
33		be B.y, but B is unavailable at toplevel, then A.t gets printed as
34		"?.B.t" although the perhaps more sensible solution would be to use
35		"A.t" in this case.  In other words, the prettyprinter should follow
36		a chain of DEFtycs not farther than there are corresponding toplevel
37		names in the current environment.)

42		Tag: blume-20030924-installer
43		Description:
44
45		Another installer tweak:  All the ML code for the installer is now
46		compiled during CMB.make and put into a little library called
47		$smlnj/installer.cm.  The installation then simply invokes
48
49		sml -m $smlnj/installer.cm
50
51		and everything happens automagically.
52
53		Win32:  ML code senses value of environment variable SMLNJ_HOME.
54		Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
55		and BINDIR.
56
57		The new scheme guarantees that the ML code responsible for the installation
58		is in sync with the APIs of the main system.  Also, the installer is
59		somewhat faster because the installer script is precompiled.

64		Tag: blume-20030924-synsock
65		Description:
66
67		Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
68		but excludes all non-blocking operations.  Defined SOCKET (in Basis)
69		and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
70		implementations of non-blocking operations from CML's Socket
71		structure.

76		Tag: blume-20030924-sockets
77		Description:
78
79		1. Fixed SOCKET API and implementation to match Basis spec.
80		This required changing the internal representation of sockets to one
81		that remembers (for each socket file descriptor) whether it is currently
82		blocking or non-blocking.  This state is maintained lazily (i.e., a system
83		call is made only if the state actually needs to change).
84
85		2. OS-specific details of sockets were moved into separate files, thus
86		making it possible to unify the bulk of the socket implementations
87		between Unix and Win32.
88
89		3. CML's socket API changed accordingly.
90		(Note that we need to remove non-blocking functions from this API
91		since they are redundant in the case of CML!)
92
93		4. CML's socket implementation now makes use of non-blocking functions
94		provided by Basis, thus removing all OS-dependent code from this part
95		of CML.
96
97		5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.
