Add temporary dir/file for htools import
Add temporary dir/file for htools import

In order for “git merge -s recursive -X subtree=htools” to do its
magic, an (mostly empty) directory must exist in the target tree name
‘htools’. Hence we add a temp file to it before the merge, and remove
it after that.
