 425 between revisions using common diff tools.  <em>git difftool</em> is a frontend

 461         Use the diff tool specified by &lt;tool&gt;.
 462         Valid merge tools are:
 463         araxis, bc3, diffuse, emerge, ecmerge, gvimdiff, kdiff3,
 464         kompare, meld, opendiff, p4merge, tkdiff, vimdiff and xxdiff.
 465 </p>
 466 <div class="paragraph"><p>If a diff tool is not specified, <em>git difftool</em>
 467 will use the configuration variable <tt>diff.tool</tt>.  If the
 468 configuration variable <tt>diff.tool</tt> is not set, <em>git difftool</em>
 469 will pick a suitable default.</p></div>
 470 <div class="paragraph"><p>You can explicitly provide a full path to the tool by setting the
 471 configuration variable <tt>difftool.&lt;tool&gt;.path</tt>. For example, you
 472 can configure the absolute path to kdiff3 by setting
 473 <tt>difftool.kdiff3.path</tt>. Otherwise, <em>git difftool</em> assumes the
 474 tool is available in PATH.</p></div>
 475 <div class="paragraph"><p>Instead of running one of the known diff tools,
 476 <em>git difftool</em> can be customized to run an alternative program
 477 by specifying the command line to invoke in a configuration
 478 variable <tt>difftool.&lt;tool&gt;.cmd</tt>.</p></div>
 479 <div class="paragraph"><p>When <em>git difftool</em> is invoked with this tool (either through the
 480 <tt>-t</tt> or <tt>--tool</tt> option or the <tt>diff.tool</tt> configuration variable)
 481 the configured command line will be invoked with the following
 482 variables available: <tt>$LOCAL</tt> is set to the name of the temporary
 483 file containing the contents of the diff pre-image and <tt>$REMOTE</tt>
 484 is set to the name of the temporary file containing the contents
 485 of the diff post-image.  <tt>$MERGED</tt> is the name of the file which is
 486 being compared. <tt>$BASE</tt> is provided for compatibility
 487 with custom merge tool commands and has the same value as <tt>$MERGED</tt>.</p></div>

 498         <em>git-difftool</em> ignores the configured defaults and runs
 499         <tt>$command $LOCAL $REMOTE</tt> when this option is specified.
