-# Libstrip - A utility to optimize libraries for specific executables

-# This is a surprisingly simple script that gets a list of
-# unresolved symbols in a list of executables specified on the
-# command line, and then relinks the uClibc shared object file
-# with only the those symbols and their dependencies. This
-# results in a shared object that is optimized for the executables
-# listed, and thus may not work with other executables.
-#
-# Example: optimizing uClibc for BusyBox
-# Compile uClibc and BusyBox as normal. Then, in this
-# directory, run:
-# libstrip path/to/busybox
-# After the script completes, there should be a new
-# libuClibc-0.9.5.so in the current directory, which
-# is optimized for busybox.
-#
-# How it works:
-# The uClibc Makefiles create libuClibc.so by first creating
-# the ar archive libc.a with all the object files, then links
-# the final libuClibc.so by using 'ld --shared --whole-archive'.
-# We take advantage of the linker command line option --undefined,
-# which pulls in a symbol and all its dependencies, and so relink
-# the library using --undefined for each symbol in place of
-# --whole-archive. The linker script is used only to avoid
-# having very long command lines.
