+<!--l. 14--><p class="noindent">This section describes a set of commands for creating <span
+class="cmti-10">soft paths </span>as opposed to the commands of the previous
+section, which created <span
+class="cmti-10">hard paths</span>. A soft path is a path that can still be &#8220;changed&#8221; or &#8220;molded.&#8221; Once you (or the
+<span
+class="cmcsc-10"><small
+class="small-caps">P</small><small
+class="small-caps">G</small><small
+class="small-caps">F</small></span>&nbsp;system) is satisfied with a soft path, it is turned into a hard path, which can be inserted into the resulting <span class="obeylines-h"><span class="verb"><span
+class="cmtt-10">.pdf</span></span></span>
+or <span class="obeylines-h"><span class="verb"><span
+class="cmtt-10">.ps</span></span></span> file.
+<!--l. 21--><p class="indent"> Note that the commands described in this section are &#8220;high-level&#8221; in the sense that they are not
+implemented in driver files, but rather directly by the <span
+class="cmcsc-10"><small
+class="small-caps">P</small><small
+class="small-caps">G</small><small
+class="small-caps">F</small></span>-system layer. For this reason, the commands for
+creating soft paths do not start with <span class="obeylines-h"><span class="verb"><span
+class="cmtt-10">\pgfsys@</span></span></span>, but rather with <span class="obeylines-h"><span class="verb"><span
+class="cmtt-10">\pgfsyssoftpath@</span></span></span>. On the other hand,
+as a user you will never use these commands directly, so they are described as part of the low-level
