     <title>Developing on FreeBSD</title>
 
     <para>So here we are.  System all installed and you are ready to
       start programming.  But where to start?  What does FreeBSD
       provide?  What can it do for me, as a programmer?</para>
 
     <para>These are some questions which this chapter tries to answer.
       Of course, programming has different levels of proficiency like
       any other trade.  For some it is a hobby, for others it is their
       profession.  The information in this chapter might be more aimed
       towards the beginning programmer, but may also serve to be
-      useful for the programmer setting her first steps on the FreeBSD
+      useful for the programmer taking her first steps on the FreeBSD
       platform.</para>

     <title>The BSD Vision</title>
 
     <para>To produce the best UNIX-like operating system package
       possible, with due respect to the original software tools

       <listitem><para>Do not add new functionality unless an
         implementor cannot complete a real application without
         it.</para></listitem>
 
       <listitem><para>It is as important to decide what a system is
         not as to decide what it is. Do not serve all the world's
         needs; rather, make the system extensible so that additional
         needs can be met in an upwardly compatible
         fashion.</para></listitem>
 
       <listitem><para>The only thing worse than generalizing from one
         example is generalizing from no examples at
         all. </para></listitem>
 
       <listitem><para>If a problem is not completely understood, it is
         probably best to provide no solution at all.</para></listitem>
 
       <listitem><para>If you can get 90 percent of the desired effect
         for 10 percent of the work, use the simpler
         solution.</para></listitem>
 
       <listitem><para>Isolate complexity as much as
         possible.</para></listitem>
 
       <listitem><para>Provide mechanism, rather than policy. In
         particular, place user interface policy in the client's
         hands.</para></listitem>
