Wrap (almost) any language into batch file

cmdize.bat

:: USAGE
::     cmdize name [...]
::
:: This tool converts a supported code into a batch file that can be 
:: executed without explicit invoking the executable engine. The script 
:: creates new file and places it under the same directory as the original 
:: one with the same name, replacing the original extension with ".bat". 
:: The content of the new file consists of the original file and the 
:: special header that being the "polyglot" and having some tricks to be a 
:: valid code in batch file and the wrapped code at the same time. 
::
:: FEATURES
:: It does comment on "Option Explicit" in VBScript.
:: "<?xml?>" declaration for wsf-files is expected.
:: "Option Explicit" and "<?xml?>" in a single line only are supported.
:: BOM is not supported at all.
::
:: It is possible to select an engine for JavaScript, VBScript and WSF via 
:: the command line options /E. If it is not pointed especially, CSCRIPT 
:: is used as the default engine for all JavaScript, VBScript and WSF 
:: files. Another valid engine is WSCRIPT. Additionally for JavaScript 
:: files it is possible to set another engine such as NodeJS, Rhino etc. 
:: The predefined option /E DEFAULT resets any previously set engines to 
:: the default value.
