+# Multilib notes:
+# 1. ABI_* flags control ABIs libclang* is built for only.
+# 2. clang is always capable of compiling code for all ABIs for enabled
+#    target. However, you will need appropriate crt* files (installed
+#    e.g. by sys-devel/gcc and sys-libs/glibc).
+# 3. ${CHOST}-clang wrappers are always installed for all ABIs included
+#    in the current profile (i.e. alike supported by sys-devel/gcc).
