The default.aap recipe is read without changing the current directory.
Aap changes directory only when it has found the main recipe to be read.
Thus before that the current directory is where you started Aap from.
An ":include" in default.aap would require an absolute path.

There is a much easier way: Additions that you always want to use you
can store in your own Aap startup directory.  This is explained in the
first chapter of the user manual, under "Recipe Execution Details":

1. Read the startup recipes, these define default rules and variables.
   These recipes are used:
   - default.aap from the distribution
   - all recipes matching /usr/local/share/aap/startup/*.aap
   - all recipes matching ~/.aap/startup/*.aap

Same problem, Aap can't find the recipe without an absolute path.

When the default.aap recipe is being read there is no toplevel recipe
yet.  Therefore the ":child" command doesn't work.  The error message
could be better though, I'll fix that.
