    PyInstaller

    PyInstaller

    Converts (packages) Python programs into stand-alone executables

    PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You'll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. As an example, libraries like PyQt, Django or matplotlib are fully supported, without having to handle plugins or external data files manually.

    Seed7

    Interpreter and compiler for the Seed7 programming language.

    Interpreter, compiler, libraries, documentation and examples for the Seed7 programming language. Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C/C++ and Java. In Seed7 new statements and operators can be declared easily. Functions with type results and type parameters are more elegant than a template or generics concept. Object orientation is used where it brings advantages and not in places where other solutions are more obvious. Seed7 spares no effort to support portable programming. Several driver libraries assure that the access to operating system resources such as files, directories, network, clock, keyboard, console and graphics are done in a portable way. Although Seed7 contains several concepts from other programming languages, it is generally not considered a direct descendant of any other programming language.
