+Tool-specific initialization for the Digital Mars D compiler.
+(http://digitalmars.com/d)
+
+Coded by Andy Friesen (andy@ikagames.com)
+15 November 2003
+
+There are a number of problems with this script at this point in time.
+The one that irritates me the most is the Windows linker setup.  The D
+linker doesn't have a way to add lib paths on the commandline, as far
+as I can see.  You have to specify paths relative to the SConscript or
+use absolute paths.  To hack around it, add '#/blah'.  This will link
+blah.lib from the directory where SConstruct resides.
+
+Compiler variables:
+    DC - The name of the D compiler to use.  Defaults to dmd or gdmd,
+    whichever is found.
+    DPATH - List of paths to search for import modules.
+    DVERSIONS - List of version tags to enable when compiling.
+    DDEBUG - List of debug tags to enable when compiling.
+
+Linker related variables:
+    LIBS - List of library files to link in.
+    DLINK - Name of the linker to use.  Defaults to dmd or gdmd.
+    DLINKFLAGS - List of linker flags.
+
+Lib tool variables:
+    DLIB - Name of the lib tool to use.  Defaults to lib.
+    DLIBFLAGS - List of flags to pass to the lib tool.
+    LIBS - Same as for the linker. (libraries to pull into the .lib)
