Create multishell scripts from your .tcl .sh and .ps1 scripts that are stored here.

Use the deck scriptwrap commands to generate a multishell .cmd file from your scripts. This .cmd is a 'polyglot' script - it should run when called from any of the target interpreters.

A multishell .cmd file is a cross-platform script that can easily be run on Windows and unix-like platforms.

The .cmd extension is primarily a convenience so that it can be run easily by name on windows but it is ok to either leave it as that on other platforms, or rename it appropriately.

On unix-like platforms it can be called with a bourne shell such as sh or bash.

On windows, it can also be called with sh or bash if they are available - but the usual method would be to run it under cmd.exe initially just by opening a cmd prompt and running it. This will run some windows batch script to automatically generate a corresponding .ps1 file and execution will switch to powershell 5 or powershell 7 (pwsh) if available. Subsequently the command can be run directly from powershell.

Whether called from Bourne shell, or cmd.exe or powershell - the usual payload would be your wrapped Tcl code - but it's also possible for powershell or sh/bash to be the primary payload script. Any of these languages could easily be used to detect and launch other scripts/utilities that you may distribute with your app.
