NAME
       sml - the interactive Standard ML of New Jersey system

SYNOPSIS
       sml [SML-OPTIONS] [OPTIONS] [FILES]

DESCRIPTION
       Standard ML of New Jersey is an incremental, interactive compiler that
       accepts SML declarations and expressions to be evaluated from standard
       input.

OPTIONS
       -32
           run the 32-bit version of the SML/NJ system (currently the
           default).

       -64
           run the 64-bit version of the SML/NJ system.  This option only
           applies to the x86-64 (aka amd64) architecture.

       @SMLwordsize
           echo the wordsize (i.e., either 32 or 64) of the system to standard
           output and then exit.  (This option was added in version 110.97).

       @SMLversion
           echo the command name and SML/NJ version (e.g., "sml 110.99.4") to
           standard output and then exit.

       @SMLload=IMAGE
           specifies the name of the heap-image file to load.  The heap suffix
           can be omitted as long as there there is not a file of the same
           name.

       @SMLcmdname=NAME
           set the command name; this is the value returned by
           CommandLine.name().

       @SMLsuffix
           echo the heap suffix for the system to standard output and then
           exit

       @SMLalloc=SIZE
           Specify the prefered size of the allocation area

       @SMLrun=RUNTIME
           specifies runtime system

       @SMLquiet
           load heap image silently (default)

       @SMLverbose
           show heap image load progress

       @SMLobjects
           show list of executable objects

       @SMLdebug=FILE
           write debugging info to file

       -Cctl=value
           set the control ctl to value.

       -Dname=value
           define the CM variable name to have the given value.

       -D'name
           define the CM variable name to have the value 1.

       -Uname
           remove any definition of the CM variable name.

       -H
           produce complete help listing

       -h
           produce minimal help listing

       -hlevel
           help with obscurity limit

       -S
           list all the controls along with their default value

       -slevel
           print a limited list of settings.  The number of levels of the
           control heirarchy is controled by level, with 0 printing just the
           root of the heirarchy.

       -E
           list all the controls along with their corresponding environment
           variables

       -elevel
           print a limited list of environment variables; The number of levels
           of the control heirarchy is controled by level, with 0 printing
           just the root of the heirarchy.

       -m
           switch to CM.make

       -a
           switch to CM.autoload; default

       file.cm
           run CM.make or CM.autoload on file.cm and then return to the SML
           prompt.  Which command is run is determined by the -m and -a flags.

       file.sig
           execute use file.sig before entering the SML top-level loop.

       file.sml
           (use) execute use file.sml before entering the SML top-level loop.

       file.fun
           (use) execute use file.fun before entering the SML top-level loop.
