Usage: hpxcxx --comp=ComponentName flags files
Usage: hpxcxx --exe=ApplicationName flags files
Usage: hpxcxx -c flags files

The hpxcxx command requires that you build either
a component, an application, or that you specify
the -c flag. If you are building against a debug
build, you need to specify --db.
If release-with-debug-info, specify --rd
If minsize-release specify --mr. All other flags
are passed through to the underlying C++ compiler.
