Javascript beautifier (http://jsbeautifier.org/)

Usage: jsbeautifier.py [options] <infile>

<infile> can be "-", which means stdin.
    <outfile> defaults to stdout

Input options:

-i,  --stdin                      read input from stdin

Output options:

-s,  --indent-size=NUMBER         indentation size. (default 4).
 -c,  --indent-char=CHAR           character to indent with. (default space).
 -e,  --eol=STRING                 character(s) to use as line terminators. (default newline - "\\n")
 -t,  --indent-with-tabs           Indent with tabs, overrides -s and -c
 -d,  --disable-preserve-newlines  do not preserve existing line breaks.
 -P,  --space-in-paren             add padding spaces within paren, ie. f( a, b )
 -E,  --space-in-empty-paren       Add a single space inside empty paren, ie. f( )
 -j,  --jslint-happy               more jslint-compatible output
 -a,  --space_after_anon_function  add a space before an anonymous function's parens, ie. function ()
 -b,  --brace-style=collapse       brace style (collapse, expand, end-expand)
 -k,  --keep-array-indentation     keep array indentation.
 -r,  --replace                    write output in-place, replacing input
 -o,  --outfile=FILE               specify a file to output to (default stdout)
 -f,  --keep-function-indentation  Do not re-indent function bodies defined in var lines.
 -x,  --unescape-strings           Decode printable chars encoded in \\xNN notation.
 -X,  --e4x                        Pass E4X xml literals through untouched
 -w,  --wrap-line-length                   Attempt to wrap line when it exceeds this length.
                                   NOTE: Line continues until next wrap point is found.
 -n, --end_with_newline            End output with newline

Rarely needed options:

--eval-code                       evaluate code if a JS interpreter is
                                   installed. May be useful with some obfuscated
                                   script but poses a potential security issue.

-l,  --indent-level=NUMBER        initial indentation level. (default 0).

-h,  --help, --usage              prints this help statement.
 -v, --version                     Show the version
