+      Stella is a multi-platform Atari 2600 VCS emulator released under the GNU
+      General Public License (GPL). Stella was originally developed for Linux by
+      Bradford W. Mott, and is currently maintained by Stephen Anthony. Since
+      its original release several people have joined the development team to
+      port Stella to other operating systems such as AcornOS, AmigaOS, DOS,
+      FreeBSD, IRIX, Linux, OS/2, MacOS, Unix, and Windows. The development team
+      is working hard to perfect the emulator and we hope you enjoy our effort.
+
+      As of its 3.5 release, Stella is officially donationware.
