in any package in the program are concatenated and used at link time. All the
pkg-config directives are concatenated and sent to pkg-config simultaneously
to add to each appropriate set of command-line flags.

One detail evident in the examples from the previous sections is that data in the instructions flows from left to right:
<code>MOVQ</code> <code>$0,</code> <code>CX</code> clears <code>CX</code>.
This rule applies even on architectures where the conventional notation uses the opposite direction.
