freeWrap

freeWrap is designed as a reliable app that can be used to convert TCL/TK scripts into single-file binary executable applications. Even though the app relies on the aforementioned scripts, you will be happy to learn that you do not need to have TCL/TK installed on the machines you run these executables, as it uses its own image.
The app comes with a -w wrap using option that enables you to make cross-platform programs, not necessarily for the operating system you are creating it on. For instance, you can create a binary executable for Windows by running the tool on another operating system, such as Linux.
Moreover, the program enables you to configure the special directories, file extension associations and shortcuts. While the developer states that files included must be referred to by their full path within the app, you also have the option to employ any relative path specifications as well.
In addition to creating executables, the tool can be used as a single-file WISH interpreter that you can used to run TCL/TK scripts or to create a file that solely contains the wrapped files for the application. Consequently, you can distribute smaller packages that can later be used as either a single WISH or TCLSH interpreter.
