<h2><a name="fixcrlf">FixCRLF</a></h2>
<h3>Description</h3>
<p>Adjusts a text file to local.</p>
<p>It is possible to refine the set of files that are being adjusted. This can be
done with the <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, <i>excludesfile</i> and <i>defaultexcludes</i>
attributes. With the <i>includes</i> or <i>includesfile</i> attribute you specify the files you want to
have included by using patterns. The <i>exclude</i> or <i>excludesfile</i> attribute is used to specify
the files you want to have excluded. This is also done with patterns. And
finally with the <i>defaultexcludes</i> attribute, you can specify whether you
want to use default exclusions or not. See the section on <a
href="../dirtasks.html#directorybasedtasks">directory based tasks</a>, on how the
inclusion/exclusion of files works, and how to write patterns.</p>
<p>This task forms an implicit <a href="../CoreTypes/fileset.html">FileSet</a> and
supports all attributes of <code>&lt;fileset&gt;</code>
(<code>dir</code> becomes <code>srcdir</code>) as well as the nested
<code>&lt;include&gt;</code>, <code>&lt;exclude&gt;</code> and
<code>&lt;patternset&gt;</code> elements.</p>

  <tr>
    <td valign="top">cr</td>
    <td valign="top">Specifies how carriage return (CR) characters are to
      be handled.  Valid values for this property are:
      <ul>
      <li>add: ensure that there is a CR before every LF</li>
      <li>asis: leave CR characters alone</li>
      <li>remove: remove all CR characters</li>
      </ul>
      Default is based on the platform on which you are running this task.
      For Unix platforms, the default is remove.  For DOS based systems
      (including Windows), the default is add.
      <p>
      Note: Unless this property is specified as &quot;asis&quot;, extra CR characters
      which do not precede a LF will be removed.</p>

  </tr>
  <tr>
    <td valign="top">eof</td>
    <td valign="top">Specifies how DOS end of file (control-Z) characters are
      to be handled.  Valid values for this property are:

<h3>Examples</h3>
<pre>  &lt;fixcrlf srcdir=&quot;${src}&quot;
       cr=&quot;remove&quot; eof=&quot;remove&quot;
       includes=&quot;**/*.sh&quot;
  /&gt;</pre>
<p>Removes carriage return and eof characters from the shell scripts.  Tabs and
spaces are left as is.</p>
<pre>  &lt;fixcrlf srcdir=&quot;${src}&quot;
       cr=&quot;add&quot;
       includes=&quot;**/*.bat&quot;
  /&gt;</pre>
<p>Ensures that there are carriage return characters prior to evey line feed.
Tabs and spaces are left as is.
EOF characters are left alone if run on
DOS systems, and are removed if run on Unix systems.</p>
<pre>  &lt;fixcrlf srcdir=&quot;${src}&quot;
       tabs=&quot;add&quot;
       includes=&quot;**/Makefile&quot;
  /&gt;</pre>
<p>Adds or removes CR characters to match local OS conventions, and
converts spaces to tabs when appropriate.  EOF characters are left alone if
run on DOS systems, and are removed if run on Unix systems.
Many versions of make require tabs prior to commands.</p>
<pre>  &lt;fixcrlf srcdir=&quot;${src}&quot;
       tabs=&quot;remove&quot;
       includes=&quot;**/README*&quot;
  /&gt;</pre>
<p>Adds or removes CR characters to match local OS conventions, and
