= Digital Mars C/C++ Compiler

The `dmc` module supports the http://www.digitalmars.com/[Digital Mars
C++ compiler.]

The module is initialized using the following syntax:

----
using dmc : [version] : [c++-compile-command] : [compiler options] ;
----

This statement may be repeated several times, if you want to configure
several versions of the compiler.

If the command is not specified, Boost.Build will search for a binary
named `dmc` in PATH.

The following options can be provided, using
_`<option-name>option-value syntax`_:

`cflags`::
Specifies additional compiler flags that will be used when compiling C
sources.

`cxxflags`::
Specifies additional compiler flags that will be used when compiling C++
sources.

`compileflags`::
Specifies additional compiler flags that will be used when compiling both C
and C++ sources.

`linkflags`::
Specifies additional command line options that will be passed to the linker.
