 Porting applications from glibc to uClibc-ng typically involves just
 recompiling the source code.  uClibc-ng even supports shared libraries and

 uClibc-ng strives to be standards compliant, which means that most
-documentation written for SuSv3, or for glibc also applies to
-uClibc-ng functions.  However, many GNU extensions are not supported
-because they have not been ported, or more importantly, would
-increase the size of uClibc-ng disproportional to the added
-functionality.

-# 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.
