# $(RC_ARCHS:%=-arch %) is a substitution reference. It denotes, in this case,
# for every value <val> in RC_ARCHS, replace it with "-arch <val>". Substitution
# references have the form $(var:a=b). We can insert the strip and prebinding commands
# into CFLAGS (and CXXFLAGS). This controls a lot of the external variables so we don't
# need to directly modify the ICU files (like for CFLAGS, etc).

# Headers
#################################

# For installhdrs. Not every compiled module has an associated header. Normally,
# ICU installs headers as a sub-targe of the install target. But since we only want
# certain libraries to install (and since we link all of our own .o modules), we need
# invoke the headers targets ourselves. This may be problematic because there isn't a
# good way to dist-clean afterwards...we need to do explicit dist-cleans, especially if
# install the extra libraries.

#################################
# Install
#################################

# For install. We currently don't install EXTRA_LIBS. We also don't install the data 
# directly into the ICU library. It is now installed at /usr/share/icu/*.dat. Thus we 
# don't use DATA_OBJ anymore. This could change if we decide to move the data back into
# the icucore monolithic library.

# This may or may not be an appropriate name for the icu dylib. This naming scheme is

# sub-version variables as needed. The Core version should be 'A' until the core
# version changes it's API...that is a new version isn't backwards compatible.
# The ICU version/subversion should reflect the actual ICU version.

# Since our sources are in icuSources (ignore the ICU subdirectory for now), we wish to

# to remove the .cvsignore files also.
