This should be done so that any attributes for ignoring certain files
when exporting can be appended to the file during the extraction step,

empty are left laying around. This later chokes the `mv` which puts the
"reduced" directory into place. Remove the empty directories as well.

This script scans Boost headers in order to determine inter-library
dependencies, using the "autolink" information embedded in the
headers for automatic linking on Windows. This information is then
