Under the hood and supported OSes
Being written in the C++ and Java programming languages, Apache OpenOffice is a platform-independent application that supports Linux, Windows and Mac OS X operating systems, running on both 64-bit and 32-bit architectures. It was also successfully ported to FreeBSD, Solaris (x86/SPARC), OS/2 and Mac OS X PowerPC.
Under the hood, Apache OpenOffice is translated in over 170 languages, provides support for system C++ STL, unified menu API, and the Python programming language. It is also very important to mention here that the well known LibreOffice open source office suite is based on the source code of this application.
Ever since the Oracle Corporation acquired the Sun Microsystems company, work on Apache OpenOffice ceased, and various developers who worked on the project decided to create a new project, named LibreOffice.
Because of this, LibreOffice is now the main choice for any Linux distribution developer who wants to pre-install a complete and open source office suite application in their operating system(s).
