Pynsist is a tool that packages Python applications into Windows installers. When you list the entry point and dependency packages in a configuration file, it creates an NSIS script that includes the embeddable Python distribution of the specified version, the packages, icons, and Start menu shortcuts, and generates an installer (.exe). Unlike PyInstaller, which freezes code into a single executable, it ships the Python interpreter as is, so the structure is simple and problems are easy to trace, and it can build Windows installers on Linux as well.
