# input variables:
#

#
#  GNUSTEP_SHARED_BUNDLE_RESOURCE_PATH : the path to the local
#  resource bundle (this might be a subdirectory of the actual bundle
#  directory).  This path must include GNUSTEP_BUILD_DIR.  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,
#  $(GNUSTEP_BUILD_DIR)/Resources/$(GNUSTEP_INSTANCE).  This variable
#  is used during build, to copy the resources in place.
#
#  GNUSTEP_BUILD_DIR : Implicitly used to find the bundle.
#
#  GNUSTEP_SHARED_BUNDLE_MAIN_PATH : the path to the top level bundle
#  directory to install, relative to GNUSTEP_BUILD_DIR during build
#  (and installation dir when installed).  For example, for a normal
#  bundle it would be $(BUNDLE_DIR_NAME); for an application it would
#  be $(APP_DIR_NAME); for a library or a tool,
#  Resources/$(GNUSTEP_INSTANCE).
#
#  GNUSTEP_SHARED_BUNDLE_INSTALL_DIR : the path to the dir
#  in which the bundle is to be installed.  For example, for a normal
#  bundle it would be $(BUNDLE_INSTALL_DIR); for an application it would
#  be $(APP_INSTALL_DIR); for a library or tool, $(LIBRARY_INSTALL_DIR),
#  or $(TOOL_INSTALL_DIR).
#
#  $(GNUSTEP_INSTANCE)_RESOURCE_FILES : a list of resource files to install.
#  They are recursively copied (/symlinked), so it might also include dirs.
#
#  $(GNUSTEP_INSTANCE)_RESOURCE_DIRS : a list of additional resource dirs
#  to create.
#
#  $(GNUSTEP_INSTANCE)_LANGUAGES : the list of languages of localized resource
#  files
#
#  $(GNUSTEP_INSTANCE)_LOCALIZED_RESOURCE_FILES : a list of localized
#  resource files to install.
#
#  $(GNUSTEP_INSTANCE)_LOCALIZED_RESOURCE_DIRS : a list of additional localized
#  resource dirs to create.
#
#  $(GNUSTEP_INSTANCE)_COMPONENTS : a list of directories which are
#  recursively copied (/locally symlinked if symlinks are available)
#  into the resource bundle.  Basically, they are currently added to
#  $(GNUSTEP_INSTANCE)_RESOURCE_FILES.
#
#  $(GNUSTEP_INSTANCE)_LOCALIZED_COMPONENTS : a list of localized
#  directories which are recursively copied (/locally symlinked if
#  symlinks are available) into the resource bundle.  Currently, they
#  are simply added to $(GNUSTEP_INSTANCE)_LOCALIZED_RESOURCE_FILES.
#
#  $(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_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)_WEBSERVER_LOCALIZED_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.
#

#  shared-instance-bundle-copy_into_dir

#
# Warning - the bundle install rules depend on the rule to create
# $(GNUSTEP_SHARED_BUNDLE_INSTALL_DIR) - the rule to build it has to be
# provided by the caller {we can't provide two rules to build the same
# target; the caller might need to provide the rule for cases when we
# are not included, so we let the caller always provide it}

#
# 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.

# Please note that if xxx/yyy is specified in RESOURCE_FILES, we
# create the file {bundle}/yyy (not {bundle}/xxx/yyy), because people
# usually can put resource files in subdirs, and want to copy them
# just top-level.  That is what currently happens, but often enough
# you might want the other behaviour ({bundle}/xxx/yyy to be created),
# and TODO: devise a way to support it.
#
# If instead xxx/yyy is specified in LOCALIZED_RESOURCE_FILES, we
# create the file {bundle}/Language.lproj/xxx/yyy, because we want to
# mirror the Language.lproj directory faithfully.  There is no
# possible confusion here.
#
# Important: we pass the '-f' argument to 'cp' to make sure that you
# can write and overwrite RESOURCE_FILES which are -r--r--r--.

# In the following rule, tar has the 'h' option, which dereferences
# symbolic links.  The idea is that you could specify symbolic links
# to some templates as some of the resource files; then building the
# bundle is quick, because you only copy the symlinks - not the actual
# files; and the symlinks are dereferenced when the bundle is
# installed (which is why the 'h' option is there).  I've never used
# this feature, but it was requested by some of our users.
#

# Another common request is to ignore/drop CVS and .svn
# directories/files from the bundle when installing.  You don't really
# want to install those in case they ended up in the bundle when you
# recursively copied some resources in it from your source code.
# This is obtained by using the 'X' flag.
# 
# Because of compatibility issues with older versions of GNU tar (not
# to speak of non-GNU tars), we use the X option rather than the
# --exclude= option.  The X option requires as argument a file listing
# files to exclude.  We use a standard exclude file list which we store
# in GNUSTEP_MAKEFILES.
