With 'nixstaller' you can easily make installers for Unix-like systems. Some of the project goals: support for many different platforms, support for different (optional) frontends used by the installer (currently FLTK, ncurses, GTK 2, and Qt are planned), ease of use for the install creator and the end user, different ways of installing (extract files to a location, compile software on the user's system, and maybe even integration for the package manager running on the user's system). Nixstaller can be fully translated and is programmed in C++ and sh.
aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, BitTorrent, and Metalink. It has a powerful segmented downloading ability, downloading a file from multiple sources and multiple protocols and utilizing your download bandwidth to the maximum. It supports downloading a file from HTTP(S)/FTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.
