Summary
-------
Exports and converts *waf* project data, for C/C++ programs, static- and shared
libraries, into **Microsoft Visual Studio**, also known as **msdev**, 
project files (.vcproj) and solution (.sln) files.

**Microsoft Visual Studio** is a mature and stable integrated development 
environment for, amongst others, the C and C++ programming language. A free
version of this IDE, known as the *express* version can be obtained from Microsoft
at http://wwww.visualstudio.com.

Description
-----------
When exporting *waf* project data, a single **Visual Studio** solution will be
exported in the top level directory of your *WAF* build environment. This 
solution file will contain references to all exported **Visual Studio** 
projects and will include dependencies between those projects and will have the
same name as APPNAME variable from the top level *wscript* file.

For each single task generator (*waflib.TaskGenerator*), for instance a 
*bld.program(...)* which has been defined within a *wscript* file somewhere in
the build environment, a single **Visual Studio** project file will be generated
in the same directory as where the task generator has been defined.
The name of this task generator will be used as name for the exported **Visual
Studio** project file. If for instance the name of the task generator is 
*hello*, then a **Visual Studio** project file named *hello.vcproj* will be
exported.

Example below presents an overview of an environment in which **Visual Studio** 
files already have been exported::

        .
        ├── components
        │   └── clib
        │       ├── program
        │       │   ├── cprogram.vcproj
        │       │   └── wscript
        │       ├── shared
        │       │   ├── cshlib.vcproj
        │       │   └── wscript
        │       └── static
        │           ├── cstlib.vcproj
        │           └── wscript
        │
        ├── waf.vcproj
        ├── appname.sln
        └── wscript


Projects will be exported such that they will use the same settings and 
structure as has been defined for that build task within the *waf* build 
environment as much as possible. Note that since cross compilation is not 
really supported in this IDE, only the first environment encountered that
is targeted for **MS Windows** will be exported; i.e. an environment in 
which::

    bld.env.DEST_OS == 'win32'

is true.


Please note that in contrast to a *normal* IDE setup the exported projects 
will contain either a *debug* **or** a *release* build target but not both at
the same time. By doing so exported projects will always use the same settings
(e.g. compiler options, installation paths) as when building the same task in
the *waf* build environment from command line.


Usage
-----
**Visual Studio** project and workspace files can be exported using the *msdev* 
command, as shown in the example below::

    $ waf msdev

When needed, exported **Visual Studio** project- and solution files can be 
removed using the *clean* command, as shown in the example below::

    $ waf msdev --clean

Once exported simply open the *appname.sln* using **Visual Studio**
this will automatically open all exported projects as well.

Tasks generators to be excluded can be marked with the *skipme* option 
as shown below::

    def build(bld):
        bld.program(name='foo', src='foobar.c', msdev_skip=True)
