- -s, --indent-size=NUMBER indentation size. (default 4).
- -c, --indent-char=CHAR character to indent with. (default space).
- -t, --indent-with-tabs Indent with tabs, overrides -s and -c
- -d, --disable-preserve-newlines do not preserve existing line breaks.
- -j, --jslint-happy more jslint-compatible output
- -b, --brace-style=collapse brace style (collapse, expand, end-expand)
- -k, --keep-array-indentation keep array indentation.
- -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.

-Rarely needed options:
-
- --eval-code evaluate code if a JS interpreter is

- script but poses a potential security issue.
-
- -l, --indent-level=NUMBER initial indentation level. (default 0).

-# UNPACKERS SPECIFICATIONS
-
-Nothing very difficult: an unpacker is a submodule placed in the directory
-where this file was found. Each unpacker must define three symbols:
-
- * `PRIORITY` : integer number expressing the priority in applying this
- unpacker. Lower number means higher priority.
- Makes sense only if a source file has been packed with
- more than one packer.
- * `detect(source)` : returns `True` if source is packed, otherwise, `False`.
- * `unpack(source)` : takes a `source` string and unpacks it. Must always return
- valid JavaScript. That is to say, your code should look
- like:
-
-```
-if detect(source):
- return do_your_fancy_things_with(source)
-else:
- return source
-```
-
-*You can safely define any other symbol in your module, as it will be ignored.*
-
-`__init__` code will automatically load new unpackers, without any further step
-to be accomplished. Simply drop it in this directory.
