title: Question related to find/replace using propertyregex
body: <p>In my ant build file, I have a property 'Version' that contains the version. Ex. <strong>2.5.17.230</strong></p>
  
  <p>Now, I am using <code>propertyregex</code> of ant-contrib to replace all '.' (dot) characters with an underscore. I have written the statement as follows:</p>
  
  <p><code>&lt;propertyregex property="Version" input="${Version}" regexp="." replace="_" global="true" /&gt;</code></p>
  
  <p>However, it does not work. I have even tried these in vain:
  <code>regexp="\."</code> and <code>regexp="[.]"</code></p>
  
  <p>Can someone please help?</p>
  
  <p>Thanks</p>
