[section Hello]

[import jamroot.jam]

This example shows a very basic Boost Build project set up so it compiles a
single executable from a single source file.

Files:

* [@../../example/hello/hello.cpp hello.cpp]
* [@../../example/hello/jamroot.jam jamroot.jam]

Our `jamroot.jam` is minimal and only specifies one `exe` target for the
program:

[jamroot]

Building the example yields:

[teletype]
```
> cd /example/hello
> b2
...found 8 targets...
...updating 4 targets...
common.mkdir bin/clang-darwin-4.2.1
common.mkdir bin/clang-darwin-4.2.1/debug
clang-darwin.compile.c++ bin/clang-darwin-4.2.1/debug/hello.o
clang-darwin.link bin/clang-darwin-4.2.1/debug/hello
...updated 4 targets...
> bin/clang-darwin-4.2.1/debug/hello 
Hello!
```

[note The actual paths in the `bin` sub-directory will depend on your
toolset.]
