The program can be used from a Windows graphical user interface that also features shell integration, or from a command-line interface as the command 7z that offers cross-platform support (see versions for details). An obsolete port of 7-Zip to POSIX systems was called p7zip. Most of the 7-Zip source code is under the LGPL-2.1-or-later license; the unRAR code, however, is under the LGPL-2.1-or-later license with an "unRAR restriction", which states that developers are not permitted to use the code to reverse-engineer the RAR compression algorithm.
