rtldi is an ELF program interpreter that makes it possible for executables to use their own ld-linux.so.2 and libc.so.6 and associated shared libraries, independent of the default versions installed in /lib and any other executable. It facilitates the simultaneous interoperation of programs that were originally linked using different generations of glibc6. In theory it should not be necessary, but in practice glibc6 has not always been backward compatible.
Wine-doors is an application designed to make installing Windows software on Linux, Solaris, or other Unix systems easier. It is essentially a package management tool for Windows software on Unix systems. It is developed and styled to fit in with the GNOME desktop, but is fairly portable and a user interface could be developed for KDE. The main goals are to replace winetools, allow flexible application management, provide Queue processing capabilities, provide Application Database integration, avoid global native overrides, automatically add items to the desktop menus, and allow users to manage their Windows applications with profiles and bottles.
