Internal markup reworking to fix the extraneous whitespace problem in the "tidy generated" web site pages. Essentially replace all ocurrences of <para><screen> with <screen> (and of course the matching closing tags).

2<title>About $LFS</title>

5<para>Please read the following paragraphs carefully. Throughout this book the
6variable LFS will be used frequently. $LFS must at all times be replaced with
7the directory where the partition that contains the LFS system is mounted. How
8to create and where to mount the partition will be explained in full detail in
9Chapter 3. For the moment let's assume that the LFS partition is mounted on
10<filename>/mnt/lfs</filename>.</para>
11
12<para>When you are told to run a command like
13<userinput>./configure --prefix=$LFS/tools</userinput>, you actually have to
14execute <userinput>./configure --prefix=/mnt/lfs/tools</userinput>.</para>
15
16<para>It's important that this is done no matter where it is read; be it in
17commands entered in a shell, or in a file edited or created.</para>
18
19<para>A possible solution is to set the environment variable LFS.
20This way $LFS can be entered literally instead of replacing it with
21/mnt/lfs. This is accomplished by running: </para>
22
23<screen><userinput>export LFS=/mnt/lfs</userinput></screen>
24
25<para>Now, if you are told to run a command such as
26<userinput>./configure --prefix=$LFS/tools</userinput>, then you may type it
27literally. Your shell will replace "$LFS" with "/mnt/lfs" when it processes
28the command line (that is, when you hit Enter after having typed the
29command).</para>
