Icecast is a streaming media server which currently supports Ogg (Vorbis and Theora), Opus, WebM and MP3 audio streams. It can be used to create an Internet radio station or a privately running jukebox and many things in between. It is very versatile in that new formats can be added relatively easily and supports open standards for communication and interaction. This package includes Ezstream, a command line source client for Icecast media streaming servers.
The Z shell (Zsh) is a Unix shell that can be used as an interactive login shell and as a command interpreter for shell scripting. Zsh is an extended Bourne shell with many improvements, including some features of Bash, ksh, and tcsh. This variant comes with statically linked zsh modules like zsh/regex to ease the consumption of existing scripts relying on such modules. It has a slightly larger memory footprint compared to the package without modules which may not be desirable for lower-end devices with less RAM.
