Depending on your preference for macros, run "info m4" or "info cpp" to read the documentation.
You can use both. You can run them more than once, perhaps changing the source with a sed or perl script between passes.

In particular, they prevent unpaired delimiters from appearing in the macro expansion and name collisions between the macro implementation and the callsite.
