Create git repositories in all leaf directories. Useful for setting up large multi-project builds with Gradle, for example.

# # find all the LEAF directories that don't have .git somewhere along the path
# selection of LEAFs is done in the awk part
# the output of find is read line by line, assuming filenames don't have newlines
# `find -print0` wouldn't work, as this would screw up the awk part
find . -not \( -name .git -prune \) -type d -print | sort -r | awk 'a!~"^"$0{a=$0;print}' | sort | while read -d $'\n' file
