[Xastir] New stable release out: xastir-2.0.4

[Chip Griffin]

From Wikipedia (for what it's worth):

> OS X is based upon the Mach kernel. Certain parts from FreeBSD's and NetBSD's implementation of Unix were incorporated in NeXTSTEP, the core of Mac OS X. NeXTSTEP was the graphical, object-oriented, and UNIX-based operating system developed by Steve Jobs' company NeXT after he left Apple in 1985.[14] While Jobs was away from Apple, Apple tried to create a "next-generation" OS through the Taligent,Copland and Gershwin projects, with little success.[15]


> OS X's core is a POSIX compliant operating system (OS) built on top of the XNU kernel, with standard Unix facilities available from thecommand line interface. Apple has released this family of software as a free and open source operating system named Darwin. On top of Darwin, Apple layered a number of components, including the Aqua interface and the Finder, to complete the GUI-based operating system which is OS X.[24]

> Since OS X is POSIX compliant, many software packages written for the *BSDs, Linux, or other Unix-like systems can be recompiled to run on it. Projects such as Homebrew, Fink, MacPorts and pkgsrc provide pre-compiled or pre-formatted packages. From version 10.3 to version 10.7, OS X included X11.app, Apple's version of the X Window System graphical interface for Unix applications, as an optional component during installation.[40] Up to and including Mac OS X v10.4 (Tiger), Apple's implementation was based on the X11 LicensedXFree86 4.3 and X11R6.6. All bundled versions of X11 feature a window manager which is similar to the OS X look-and-feel and has fairly good integration with Mac OS X, also using the native Quartz rendering system. Earlier versions of OS X (in which X11 has not been bundled) can also run X11 applications using XDarwin. With the introduction of version 10.5 Apple switched to the X.org variant of X11.[41] Version Mac OS X 10.7 "Lion" uses X.org Server version 1.10.x[42] Starting with OS X Mountain Lion, X11 is not bundled in OS X; instead, it has to be installed from, for example, the open source XQuartz project.[43]
