...Far Manager works in text mode and provides a simple and intuitive interface for performing most of the necessary actions: viewing files and directories; editing, copying and renaming files; and many other actions.
Far Manager has a multi-language, easily configurable interface. File system navigation is made easier through the use of color highlighting and sort groups.
The functionality of Far Manager is greatly extended by external DLL modules — plugins (made possible by a special set of interfaces — the Plugins API). For example: archive support, FTP client, temporary panel and network browser are all implemented as plugins included in the standard distribution of Far.
OpenPoplog is a multi-language, incrementally-compiled virtual machine-based development environment with its own extensive teaching and support material, supporting the languages Pop-11, Prolog, Common Lisp and ML on Unix, VMS, Linux and Windows.
