 System requirements
 ===================
 
-Compiling the mlt tool requires a "working version" of SML/NJ. I've
-tested it with 110.42. You'll need to get the SML/NJ source code
-package and modify some of the included .cm files to make a few
-additional internal structures visible. The necessary changes to make
-are described below, with paths given relative to your base SML/NJ
-directory. The lines listed for each file should be added right before
-the "is" keyword at the end of the exports list for a library. The
-"is" is on the first non-indented line after the initial "Library"
-line in each of these files.
-
-The following lines to src/compiler/core.cm:
-       structure Types
-       structure EntityEnv
-       structure Modules
-       structure Stamps
-       structure Bindings
-       structure TypesUtil
-       structure VarCon
-       structure ModuleUtil
-       structure II
-       structure BasicTypes
-       structure PPType
-       structure Access
-
-The following lines to both src/system/smlnj/compiler/current.cm
-and src/system/smlnj/compiler/x86.cm:
-       structure Types
-       structure EntityEnv
-       structure Modules
-       structure Stamps
-       structure Bindings
-       structure TypesUtil
-       structure VarCon
-       structure ModuleUtil
-       structure II
-       structure BasicTypes
-       structure PPType
-       structure Access
-       structure Unify
-
-The following line to src/compiler/Elaborator/elaborate.cm:
-       structure Unify
-
-Finally, add the following line somewhere _below_ the "is" in
-src/system/smlnj/compiler/x86.cm:
-       $smlnj/viscomp/elaborate.cm
-
-After making these changes, you can rebuild and install the compiler
-with the following sequence of commands:
-
-cd $smlnjdir/src/system
-sml
-CM.autoload "$smlnj/cmb.cm";
-CMB.make ();
-<exit from sml by typing the end-of-file sequence>
-./makeml
-./installml
+Compiling the mlt tool requires a "working version" of SML/NJ. It's
+best to use version 110.49 or later. Earlier versions have
+incompatibilities, bugs, or both. You may have problems with any
+version whatsoever, though, since this stuff uses some SML/NJ compiler
+internals, and they may change often.
 
 
 =============
 Configuration
 =============
 
+Modify the parameters in settings.sml as appropriate for your system.

 If it is possible for you to modify a file /etc/mlt.conf, then you
 can edit this file to set various options related to locations of
 important files on your file system. In particular, you may want to
