"""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
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)
