      <dt>Explanation:</dt>

      <dd>The <tt>svn copy</tt> command schedules a file or directory
      for addition to the repository, recording the "source" of the
      copy.  After committing, <tt>svn log</tt> on the copied item
      will trace history back through the original copy-source.  The
      <tt>svn move</tt> command is exactly equivalent to running
      <tt>svn copy</tt>, followed by an <tt>svn delete</tt> on the
      copy-source: the result is a new item scheduled for addition
      (with copy-history attached) and the original item scheduled for
      deletion.</dd>

<h2>Finding the beginning of a branch</h2>

<p>If you're attempting to merge an entire branch into another, you
need to compare the "root" and "tip" of the source branch, and then
merge those differences into a working copy of the target branch.
Obviously the "tip" of the branch can be represented by using the
<tt>HEAD</tt> keyword.  But how do you find the "birth" revision of
the source branch?</p>

<p>The easiest solution is to run</p>

<pre>
   $ svn log -v --stop-on-copy source-branch-URL
   &hellip;
</pre>

<p>This command will display every change ever made to the branch, but
<tt>--stop-on-copy</tt> option will cause the output to stop as soon
as detects a copy operation in the branch's history.  By definition,
then, the very last log entry printed will show the copy being made.
It will look something like:</p>

<pre>
r9189 | joe | 2004-03-22 10:10:47 -0600 (Mon, 22 Mar 2004) | 1 line
Changed paths:
   A /branches/mybranch (from /trunk:9188)
</pre>

<p>In this case, you would then know to compare revisions 9189 and
HEAD of the branch in order to perform the merge:</p>

<pre>
   $ svn merge -r9189:HEAD source-branch-URL target-branch-WC
   &hellip;
</pre>
