Essentially I want to be able to distribute a custom script and it seems that I cannot create a .tbx file, so I looked into the other methods, but they are all only for Python modules it seems. What I want to be able to do is have the user still be able to pull up the dialog box prompting for input when they click on the tool, how do I go about packaging the external libraries that I used for this script and distribute it such that the user can simply import the tool into his toolbox and click on it and it will pull up the dialog box for user input?
