-= ports =
+In MacPorts, the term "Universal" usually means a compiled program or library which contains object code in multiple instruction sets, so that it can run on a variety of CPUs. 
+
+In the history of macOS and MacPorts, three important kinds of "universal" binaries have been:
+
+1. x86_64 and arm (for macOS 11 and later)
+2. i386 and x86_64 (for MacOS X Tiger 10.4 through macos 13 High Sierra)
+3. ppc and i386 (for MacOS X Cheetah 10.0 through Mac OS X Leopard 10.5.8)
+
+MacPorts offers compilation to universal binaries as a default preference and in response to a `+universal` variant.  
+
+= Overview of ports with +universal variants =
+
+This is an overview list of ports with universal variants. Each entry is a link to a separate page which describes the port's behaviour when compiled with `+universal`.

  * b=broken
  * s=stable (completes the testsuite without errors)
  * t=testing (no testsuite available)
  * u=undecided (the testsuite fails or doesn't compile, the program seems to work as expected, though)
