+A wrapper around the linker for 68K programs; it supplies a linker script,
+invokes the linker, and converts the resulting ELF binary to a Mac APPL with

+### LaunchAPPL
+
+A tool for lauching compiled Mac applications via various emulators.
+Currently, there are the following backends:
+
+* classic - launch in the Classic environment on PowerPC Macs up to Tiger (10.4)
+* carbon - launch as a Carbon app on PowerPC Macs and via Rosetta on Intel Macs up to Snow Leopard (10.6)
+* minivmac - launch using the Mini vMac emulator
+* executor - launch using Executor

+**CONTRIBUTION OPPORTUNITY** - This tool can easily be extended with further backends,
+so make it work with your favourtite emulator.
