+/* ============== original README ===================
+ *
+ * sstrip is a small utility that removes the contents at the end of an
+ * ELF file that are not part of the program's memory image.
+ *
+ * Most ELF executables are built with both a program header table and a
+ * section header table. However, only the former is required in order
+ * for the OS to load, link and execute a program. sstrip attempts to
+ * extract the ELF header, the program header table, and its contents,
+ * leaving everything else in the bit bucket. It can only remove parts of
+ * the file that occur at the end, after the parts to be saved. However,
+ * this almost always includes the section header table, and occasionally
+ * a few random sections that are not used when running a program.
+ *
+ * It should be noted that the GNU bfd library is (understandably)
+ * dependent on the section header table as an index to the file's
+ * contents. Thus, an executable file that has no section header table
+ * cannot be used with gdb, objdump, or any other program based upon the
+ * bfd library, at all. In fact, the program will not even recognize the
+ * file as a valid executable. (This limitation is noted in the source
+ * code comments for bfd, and is marked "FIXME", so this may change at
+ * some future date. However, I would imagine that it is a pretty
+ * low-priority item, as executables without a section header table are
+ * rare in the extreme.) This probably also explains why strip doesn't
+ * offer the option to do this.
+ *
+ * Shared library files may also have their section header table removed.
+ * Such a library will still function; however, it will no longer be
+ * possible for a compiler to link a new program against it.
+ *
+ * As an added bonus, sstrip also tries to removes trailing zero bytes
+ * from the end of the file. (This normally cannot be done with an
+ * executable that has a section header table.)
+ *
+ * sstrip is a very simplistic program. It depends upon the common
+ * practice of putting the parts of the file that contribute to the
+ * memory image at the front, and the remaining material at the end. This
+ * permits it to discard the latter material without affecting file
+ * offsets and memory addresses in what remains. Of course, the ELF
+ * standard permits files to be organized in almost any order, so if a
+ * pathological linker decided to put its section headers at the top,
+ * sstrip would be useless on such executables.
