 This source can be compiled for three different types of interface:
 
-  --enable-svgalib
-  --enable-allegro
-  --enable-tcltk (deprecated - will re-write soon)
+  --with-svgalib
+  --with-allegro
+  --with-gtk
+  --with-tcltk (deprecated)
+
+One and only one of these options must be given to configure.
+
+The source also needs a z80 emulation:
+
+  --with-raze  (i386 assembler - uses nasm to compile)
+  --with-cmz80 (portable C)
 
 One and only one of these options must be given to configure.

 An example compilation:
 
-  ./configure --enable-svgalib --with-gcc=3 --prefix=/home/james

   make
   make install
 
+Cross compile
+=============
+
+Generator's build tree should cope well with cross compilation.  To
+compile using djgpp/allegro use:
+
+  PATH=/usr/i586-pc-msdosdjgpp/bin:$PATH ./configure --with-allegro \
+    --with-raze --host=i586-pc-msdosdjgpp --build=i686-pc-linux-gnu \
+    --with-coffasm
+  PATH=/usr/i586-pc-msdosdjgpp/bin:$PATH make
+
+The option --with-coffasm is for raze compilation - it does two things,
+it switches to 'coff' output instead of 'elf' with nasm, and it also
+modifies a macro in raze.asm that inserts underscores before all globals.
+
+Generator has two binaries 'def68k' and 'gen68k' that need to be run on
+the host machine, so if you see the error:
+
+  ./def68k: ./def68k: cannot execute binary file
+
+You will need to copy local versions of def68k and gen68k (that you compiled
+earlier) into place so that the compilation can continue.
