<title>Introduction</title>
<para>This part is divided into three stages: first, building a cross
compiler and its associated libraries; second, using this cross toolchain
to build several utilities in a way that isolates them from the host
distribution; and third, entering the chroot environment (which further improves
host isolation) and constructing the remaining tools needed to build the final
system.</para>
<important><para>This is where the real work of building a new system
begins. Be very careful to follow the instructions exactly as the book
shows them. You should try to understand what each command does,
and no matter how eager you are to finish your build, you should
refrain from blindly typing the commands as shown. Read the documentation when
there is something you do not understand. Also, keep track of your typing
and of the output of commands, by using the <command>tee</command> utility
to send the terminal output to a file. This makes debugging easier
if something goes wrong.</para></important>
<para>The next section is a technical introduction to the build process,
while the following one presents <emphasis role="strong">very
important</emphasis> general instructions.</para>
