+## Using boost::throw_with_location
+
+This example demonstrates a trivial use of `boost::throw_with_location`. Since
+a source location is not supplied, the location of the call to
+`boost::throw_with_location` is implicitly captured.
+
+[source,c++,linenums,highlight=9]
+----
+#include <boost/throw_exception.hpp>
+#include <boost/core/verbose_terminate_handler.hpp>
+#include <stdexcept>
+
+int f1( int x )
+{
+    if( x < 0 )
+    {
+        boost::throw_with_location(
+            std::invalid_argument( "f1: x cannot be negative" ) );
+    }
+
+    return x;
+}
+
+int main()
+{
+    std::set_terminate( boost::core::verbose_terminate_handler );
+
+    return f1( -4 );
+}
+----
+
+Sample output:
+
+```none
+std::terminate called after throwing an exception:
+
+      type: boost::detail::with_throw_location<std::invalid_argument>
+    what(): f1: x cannot be negative
+  location: <source>:9:9 in function 'f1'
+```
+
+## Using boost::throw_with_location with an explicit source location
+
+In this example, the call to `boost::throw_with_location` is moved into
+a common helper function. Note how the "API" functions `f1` and `f2`
+take a source location argument that defaults to `BOOST_CURRENT_LOCATION`.
+This allows the source location attached to the exception to point at
+the location of the call to `f2`, rather than inside of `f2`.
+
+Since functions such as `f2` are typically called from more than one place
+in the program, this is usually what we want, because it enables us to
+identify the throwing call, rather than merely to know that it was `f2`
+that threw.
