20    Fixed a bug in config/_ml-build that prevented ml-yacc and ml-lex from
21    getting installed properly (by config/install.sh).

29    !!! NEW BOOT FILES !!!
30    
31    This change is in preparation of fading out support for "implicitly
32    anchored path names".  I went through all sources and used the
33    explicit (and relatively new) $-notation.  See system/README and the
34    CM manual for more info on this.
35    
36    I also modified the anchoring scheme for some things such as "smlnj",
37    "MLRISC", "cm", etc. to take advantage of the fact that explicit
38    anchors are more expressive: anchor name and first arc do not have to
39    coincide.  This entails the following user-visible change:
40    
41    You have to write $smlnj/foo/bar instead of smlnj/foo/bar.  In
42    particular, when you fire up sml with a command-line argument, say,
43    e.g.:
44    
45       sml '$smlnj/cmb.cm'
46    
47    At the ML toplevel prompt:
48    
49       CM.autoload "$smlnj/cmb.cm";
50    
51    There is also a new controller in CM.Control that can be used to turn
52    off all remaining support for implicit anchors by saying:
53    
54        CM.autoload "$smlnj/
55        #set CM.Control.implicit_anchors false;
56    
57    This causes CM to reject implicitly anchored paths.  This is (for the
58    time being) less permissive than the "final" version where there will
59    be no more such implicit anchors and relative paths will be just that:
60    relative.
61    
62    The next step (version after next version?) will be to make the
63    default for CM.Control.implicit_anchors false.  After the dust has
64    settled, I can then produce the "final" version of this...
65    
66    Note: Since bootstrapping is a bit tricky, I provided new boot files.
