<h2>I-AM-HERE</h2>a convenient marker for use with <code><a href="REBUILD.html">rebuild</a></code>

Example Input File for Rebuild:
(defun fn1 (x y) ...)
(defthm lemma1 ...)
(defthm lemma2 ...)
(i-am-here)
The following lemma won't go through.  I started
typing the hint but realized I need to prove a
lemma first.  See the failed proof attempt in foo.bar.
I'm going to quit for the night now and resume tomorrow
from home.<p>

<p>
By putting an <code>(i-am-here)</code> form at the ``frontier'' of an evolving
file of <a href="COMMAND.html">command</a>s, you can use <code><a href="REBUILD.html">rebuild</a></code> to load the file up to the
<code>(i-am-here)</code>.  <code>I-am-here</code> simply returns an <code><a href="LD.html">ld</a></code> error triple and any
form that ``causes an error'' will do the same job.  Note that the
text of the file after the <code>(i-am-here)</code> need not be machine
readable.
