title: How do I do a search and replace on a configuration file using Wix?
body: <p>Some code I inherited has its "configuration" (if you can call it that) embedded into its PHP and ASP (don't ask) code.  Because its not an XML or INI file, I'm having the darnedest time figuring out how to modify these files at install time.  If I could, I'd like to do a simple search and replace.  I've read elsewhere (<a href="https://stackoverflow.com/questions/1186415/wix-search-and-replace-on-a-configuration-file">WiX Search and Replace on a configuration file</a>) that I should just write a Custom Action.  I'd rather avoid it if I could since the code I wish to configure is deprecated and I don't want to create yet another project to support this code.</p>
  
  <p>So is there a way to do this without writing a custom action.  If not, is anyone aware of any custom actions that are already built that could help me with this task?</p>
