-<para>Most programs and libraries are, by default, compiled with debugging
-symbols included (with gcc option -g).</para>
-
-<para>When debugging a program or library that was compiled with debugging
-information included, the debugger can give you not only memory addresses
-but also the names of the routines and variables.</para>
- 
-<para>But the inclusion of these debugging symbols enlarges a program or
-library significantly. To get an idea of the amount of space these symbols
-occupy, have a look at the following:</para>
-
-<itemizedlist>
-
-<listitem><para>a bash binary 
-with debugging symbols: 1200 KB</para></listitem>
-
-<listitem><para>a bash binary
-without debugging symbols: 480 KB</para></listitem>
-
-<listitem><para>Glibc and GCC files (/lib and /usr/lib)
-with debugging symbols: 87 MB</para></listitem>
-
-<listitem><para>Glibc and GCC files
-without debugging symbols: 16 MB</para></listitem>
-
-</itemizedlist>
-
-<para>Sizes may vary a little, depending on which compiler was used and
-which C library. But when comparing programs with and without debugging
-symbols, the difference will generally be a factor between 2 and 5.</para>
-
-<para>As most people will probably never use a debugger on their system
-software, a lot of disk space can be regained by removing these symbols .</para>
-
-<para>To remove debugging symbols from a binary (which must be an a.out
-or ELF binary), run <command>strip --strip-debug filename</command>.
-Wildcards can be used to treat multiple files (use something like
-<userinput>strip --strip-debug $LFS/tools/bin/*</userinput>).</para>
-
-<para>For your convenience, <xref linkend="chapter-finalizing"/> includes one simple
-command to strip all debugging symbols from all programs and libraries on your
-system. Additional information on optimization can be found in the hint at
-<ulink url="&hints-root;optimization.txt"/>.</para>
