+# Thoughts of generating ELF32 files
+#   * In ELF parlance, linker notes are called relocations.
+#     We need to solve relocations only when generating an
+#     executable file.
+#   * ELF symbols are defined relative to their corresponding sections'
+#     origins.  Basically, a symbol's value consists of two parts:
+#     reference to its section and its location inside the section.
+#   * We'll need some symbols to represent offsets in the generated
+#     file.  It's probably best to treat them as ELF absolute symbols.
