@# stow doesn't support __stowing?__ directories with symlinks, see:
@# https://github.com/aspiers/stow/issues/51
@# what i do here is a stow-like glue
@# - loop through all top level directories in merged
@# - for each file or directory in the top level
@# - create a symlink in $HOME pointing to merged
@# this has one important limitation: it doesn't support shared
@# nested directories as stow does. for example, if you have a directory
@# like: merged/nvim/.config/nvim, $HOME/.config would end up as a link,
@# which is not ideal since it contains other configs too!
@#
@# the solution is to never use shared directories and setup links after
@# this target with the after_stow target.
