# FIXME: Missing dependency on $(GNUSTEP_INSTANCE)Info.plist files

# You can have a single xxxInfo.plist for both GNUstep and Apple.

# Often enough, you can just put in it all fields required by both
# GNUstep and Apple; if there is a conflict, you can add
# xxx_PREPROCESS_INFO_PLIST = yes to your GNUmakefile, and provide a
# xxxInfo.cplist (please note the suffix!) - that file is
# automatically run through the C preprocessor to generate a
# xxxInfo.plist file from it.  The preprocessor will define GNUSTEP
# when using gnustep-base, APPLE when using Apple FoundationKit, NEXT
# when using NeXT/OPENStep FoundationKit, and UNKNOWN when using
# something else, so you can use
# #ifdef GNUSTEP
#   ... some plist code for GNUstep ...
# #else
#   ... some plist code for Apple ...
# #endif
# to have your .cplist use different code for each.
#

# The following is really a hack, but very elegant.  Our problem is
# that we'd like to always depend on xxxInfo.plist if it's there, and
# not depend on it if it's not there - but we don't have a solution to
# this problem at the moment, so we don't depend on it.  Adding
# xxx_PREPROCESS_INFO_PLIST = yes at the moment just turns on the
# dependency on xxxInfo.plist, which is then built from xxxInfo.cplist
# using the %.plist: %.cplist rules.

# On Apple we assume that xxxInfo.plist has a '{' (and nothing else)
# on the first line, and the rest of the file is a plain property list
# dictionary.  You must make sure your xxxInfo.plist is in this format
# to use it on Apple.

# The problem is, we need to add the automatically generated entries
# to this custom dictionary on Apple - to do that, we generate '{'
# followed by the custom entries, followed by xxxInfo.plist (with the
# first line removed), or by '}'.  NB: "sed '1d' filename" prints out
# filename, except the first line.

# On GNUstep we use plmerge which is much slower, but should probably
# be safer, because as soon as xxxInfo.plist is in plist format, it
# should always work (even if the first line is not just a '{' and
# nothing else).
