# First of all, we need to deal with a special complication, which is
# if any HEADER_FILES include a subdirectory component (allowed since
# gnustep-make 2.2.1). Ie, something like
#
# HEADER_FILES = Beauty/Pride.h
#
# This is a complication because to install such a file we first need
# to create the directory to install it into.
#
# The following command determines the install (sub)directories that
# we need to create. 'dir' extracts the directory from each file
# ("./" will be returned if there is no such subdirectory); 'sort'
# removes duplicates from the results, and makes sure that the
# directories are in the order that they should be created in
# ("Pride/" comes before "Pride/Beauty"). Finally, filter-out removes
# ./ from the results as we create the root directory separately.

#
# The second one (which you activate by setting GNUSTEP_DEVELOPER to
# yes in your shell) is the one specifically optimized for faster
# development. We only install headers which are newer than the
# installed version. This is much faster if you are developing and
# need to install headers often, and normally with just few changes.
# It is slower the first time you install the headers, because we
# install them using a lot of subshell processes (which is why it is not
# the default - `users' install headers only once - the default
# setup is for users).
