= Hello

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

Files:

* link:../../example/hello/hello.cpp[hello.cpp]
* link:../../example/hello/jamroot.jam[jamroot.jam]

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

[source,jam]
----
include::jamroot.jam[]
----

Building the example yields:

[source,console]
----
> cd /example/hello
> b2

Hello!

toolset.
