"""SCons.Tool.dmd

Tool-specific initialization for the Digital Mars D compiler.
(http://digitalmars.com/d)

Coded by Andy Friesen (andy@ikagames.com)
15 November 2003

Amended by Russel Winder (russel@russel.org.uk)
2010-02-07

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)
