## DESCRIPTION
       **acorn** is a utility to parse a JavaScript file from the command line.  It accepts as arguments
       the input file.  The utility spits out the syntax tree as JSON data.

## OPTIONS
       **--ecma3**, **--ecma5**, **--ecma6**, **--ecma7**, **...**, **--ecma2015**, **--ecma2016**
              Sets the ECMAScript version to parse.  Default is version 7.

### --tokenize
              Tokenizer mode of the parser.

### --locations
              Attaches a "loc" object to each node with "start" and "end" subobjects, each of  which
              contains the one-based line and zero-based column numbers in {line, column} form.

### --allow-hash-bang
              If enabled, skip the leading hashbang line.

### --compact
              No whitespace is used in the AST output.

### --silent
              Do not output the AST, just return the exit status.

### --module
              Indicates  the  code shouldn't be parsed as a script but as a module.  This influences
              global strict mode and 'import' and 'export' declarations.

       **--help** Print the usage information and quit.
