LSB (Linux Standard Base)

The Linux Standard Base (LSB) was created to lower the overall costs of supporting the Linux platform and porting applications to different distributions by reducing the differences between individual Linux distributions. The Linux Standard Base (LSB) is a standard core system of defined behaviors and interfaces used to standardize the structure of Linux and related operating systems. The Linux Standard Base offers interoperability between applications and the Linux operating system and enables software applications to run on any compliant system. The Linux Standard Base (LSB) is binary-compatible.LSB core specifications include Executable And Linking Format (ELF), Base and Utility Libraries, Commands and Utilities (grep, sed, awk, tar, useradd, patch, etc.), File System Hierarchy (FHS),System Initialization (cron, init scripts, etc.), etc. LSB C++ specifications include Low Level System Information and Base Libraries. LSB desktop specifications include Graphic Libraries (libX11, libSM, libICE, libXt, libXext, libXi), OpenGL Libraries, picture libraries (jpeg, png), Fontconfig library, GTK+ Stack Libraries, Qt3 Library, XML2 libraries, etc.
