logDir - - where to write the following logs:

1. stdout.log
2. stderr.log

public static Statement interpret(String... portableStatements)

statement can have multiple newlines, note you should use lf to be portable

public static Statement exec(String portableStatement)

interprets and adds a newline to the statement

public static Statement extractTargzIntoDirectory(String method,
                                  URI endpoint,

                                com.google.common.collect.Multimap<String,String> headers,
                                String directory)

unzip the data received from the request parameters.

Parameters:

method - http method: ex GET

endpoint - uri corresponding to the request

headers - request headers to send

directory -
