+*ack.txt*   Plugin that integrates ack with Vim

+INTRODUCTION                                                             *ack*
+
+This plugin is a front for the Perl module App::Ack.  Ack can be used as a
+replacement for grep.  This plugin will allow you to run ack from vim, and
+shows the results in a split window.
+
+:Ack [options] {pattern} [{directory}]                                  *:Ack*
+
+    Search recursively in {directory} (which defaults to the current
+    directory) for the {pattern}.  Behaves just like the |:grep| command, but
+    will open the |Quickfix| window for you.
+
+:AckAdd [options] {pattern} [{directory}]                            *:AckAdd*
+
+    Just like |:Ack| + |:grepadd|.  Appends the |quickfix| with the results
+
+:LAck [options] {pattern} [{directory}]                                *:LAck*
+
+    Just like |:Ack| + |:lgrep|.  Searches, but opens in |location-list|
+
+:LAckAdd [options] {pattern} [{directory}]                          *:LAckAdd*
+
+    Just like |:Ack| + |:lgrepadd|.  Searches, but appends results to
+    |location-list|
+
+Files containing the search term will be listed in the split window, along
+with the line number of the occurrence, once for each occurrence.  <Enter> on
+a line in this window will open the file, and place the cursor on the matching
+line.
