Why This Project Is Awesome

Which criterion does it meet? (pick one)

• Industry Standard - The go-to tool for a specific use case
• Rising Star - 5,000+ stars in <2 years, significant adoption
• Hidden Gem - Exceptional quality, solves niche problems elegantly

Explain:
Mentioned python, since it is mainly scripted in python. Using this tool we can build standalone executables, which is similar to pyinstaller. But we can also build installers (or install script idk what thats called) of the python application, as executables or even MSI installer for windows (niche use case). Which I though was cool.

How It Differs

As mentioned earlier, we can build installers with this program.

If similar entries exist, what makes this one unique?
Similar projects exists like pyinstaller and nukita. But you can only bundle python application into executables and to package a installer out of the executable you would need other tool. You can do both on this tool.
