19    Description:
20    
21    Added a new tool class called "lazysml" to CM's tool chest.  The only
22    difference to "sml" is that compilation is done with Control.lazysml
23    set to true.  A source of class "lazysml" is automatically recognized
24    by a file name suffix of ".lml".
25    
26    In addition to the above feature, the original class "sml" now also
27    supports a tool argument "lazy" which has the same effect.  As a
28    result, the following three lines are equivalent:
29    
30        foo.sml : lazysml
31        foo.sml : sml (lazy)
32        foo.sml (lazy)
33    
34    The setting goes into effect both during parsing and during
35    compilation.  The original setting is restored right after parsing and
36    after compilation, respectively.
37    
38    In addition to all the above, there is also a general mechanism to set
39    ANY of the "controls" that are available at the command line via
40    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
41    apply as well. (In fact, "lazy" is implemented as a special case of
42    the general mechanism.)
43    
44    The .cm file syntax uses a new keyword tool argument called "with".
45    There are several ways of indicating the desired settings:
46    
47        foo.sml (with:parser.quotations=true)
48        foo.sml (with:(name:parser.quotations value:true))
49        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
50        foo.sml (with:(name1=value1 name2=value2 ...))
51        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
52    
53        etc.
54    
55    Another possible abbreviation is to leave out the =v or value:v part
56    if the name refers to a boolean control (in which case the value is
57    taken to be true).  Thus, one could get lazy sml also by saying:
58    
59        foo.sml (with:parser.lazy-keyword=true)
60        foo.sml (with:parser.lazy-keyword)
61        foo.sml (with:(name:parser.lazy-keyword value:true))
62        foo.sml (with:(name:parser.lazy-keyword))
