# The code below has been temporarily removed, because...
# Frameworks in GNUstep-make are supported by creating a link like
# 
#   Libraries/libMyFramework.dylib ->
#      Frameworks/MyFramework.framework/Versions/Current/libMyFramework.dylib,
#
# to mitigate the fact that FSF GCC does not support a -framework flag.
#
# On Darwin, however, we partially emulate -framework by setting the
# "install_name" to the framework name during linking. The dynamic
# linker (dyld) is smart enough to find the framework under this name,
# but only if DYLD_FRAMEWORK_PATH is set (unless we set the
# "install_name" to an absolute path, which we don't). We'd really like
# to fully support -framework, though.
#
# Use otool -L MyApplication.app/MyApplication, for instance, to see
# how the shared libraries/frameworks are linked.
