 USING THE CROSS-COMPILER ON LINUX
 
-You can substitute the Windows version of the Mercury compiler binary
-(mercury_compile.exe) with a Linux version.  Again, this should be from
-the same or similar version of Mercury.
+To use the cross-compiled installation on Linux, you must provide Linux
+binaries to substitute each of the .exe files in the bin directory.
+The Linux binaries should be from the same version of the Mercury compiler.
 
-The 'mmc' shell script will have been set up to look for a binary named
-'mercury_compile' so you just need to place the Linux binary into the bin
-directory, e.g.
+For example, you can run a command such as below to hard link the binaries
