#
# input variables:
#

#
#  GNUSTEP_SHARED_INSTANCE_BUNDLE_RESOURCE_PATH : the path to the
#  local resource bundle (this might be a subdirectory of the actual
#  bundle directory).  Resource files will be copied into this path.
#  For example, for a normal bundle it would be
#  $(BUNDLE_DIR)/Resources; for an application it would be
#  $(APP_DIR)/Resources; for a library or a tool,
#  Resources/$(GNUSTEP_INSTANCE).  This variable is used during build,
#  to copy the resources in place.
#
#  GNUSTEP_SHARED_INSTANCE_BUNDLE_MAIN_PATH : the path to the top
#  level bundle directory to install.  For example, for a normal
#  bundle it would be $(BUNDLE_DIR); for an application it would be
#  $(APP_DIR); for a library or a tool, Resources/$(GNUSTEP_INSTANCE).
#
#  GNUSTEP_SHARED_INSTANCE_BUNDLE_PRESERVE_LINK_PATH : the path
#  to a symlink to preserve when installing.  Normally symlinks are
#  dereferenced, but we have support to preserve a single symlink.
#  This is used when building bundles on MacOSX.  If not set, it's
#  ignored.
#
#  $(GNUSTEP_INSTANCE)_RESOURCE_FILES : the list of resource files to install
#
#  $(GNUSTEP_INSTANCE)_RESOURCE_FILES_DIR : the directory in which the
#  resources are located.
#
#  $(GNUSTEP_INSTANCE)_RESOURCE_DIRS : the list of additional resource dirs
#  to create.
#
#  $(GNUSTEP_INSTANCE)_LANGUAGES : the list of languages of localized resource
#  files
#
#  $(GNUSTEP_INSTANCE)_LOCALIZED_RESOURCE_FILES : the list of localized
#  resource files to install
#
#  $(GNUSTEP_INSTANCE)_COMPONENTS : a list of directories which are
#  recursively copied (/locally symlinked if symlinks are available)
#  into the resource bundle. <FIXME - not sure this will be kept>
#
#  $(GNUSTEP_INSTANCE)_SUBPROJECTS : the list of subprojects is used
#  because the resources from each subproject are merged into the bundle
#  resources (by recursively copying from LLL/Resources/Subproject into
#  the GNUSTEP_SHARED_INSTANCE_BUNDLE_RESOURCE_PATH, where $(LLL) is the
#  subproject name.
#
#  GNUSTEP_TYPE : used when printing the message 'Copying resources into 
#  the $(GNUSTEP_TYPE) wrapper...'
#
# GSWeb related variables - 
#
# $(GNUSTEP_INSTANCE)_WEBSERVER_RESOURCE_FILES : a list of resource files to
# copy from the WebServerResources directory into the WebServer
# subdirectory of the resource bundle
#
# $(GNUSTEP_INSTANCE)_LOCALIZED_WEBSERVER_RESOURCE_FILES : a list of
# localized resource files to copy from the yyy.lproj subdir of the
# WebServerResources directory into the yyy.lproj subdir of the
# WebServer subdirectory of the resource bundle - this for each
# language yyy.

#
# We provide two different ways of building bundles, suited to
# different usages - normal user and developer.
#
# `Normal user` builds the bundle once.  We optimize for single-build
# in this case.
#
# `Developer` builds and rebuilds the bundle a lot of times with minor
# changes each time.  We optimize for efficient rebuilding in this
# case.
#
# The default behaviour is 'Normal user'.  To switch to 'Developer'
# mode, set GNUSTEP_DEVELOPER=YES in the environment.
#
# TODO - implement the `Developer` mode :-)
#

# Please note the trick when copying subproject resources - if there
# is nothing inside $$subproject/Resources/Subproject/, in
# $$subproject/Resources/Subproject/* the * expands to itself.  So we
# check if that is true before trying to copy.
