+// We implement a subset of the original GNU ld linker script language
+// for compatibility.  The goal is not to implement the entire
+// language.  It is merely to implement enough to handle common uses.
+// In particular we need to handle /usr/lib/libc.so on a typical
+// GNU/Linux system, and we want to handle linker scripts used by the
+// Linux kernel build.
