# Modifying Core Files?

 * I would like to make a few small changes to the way some parts of WordPress work
   on my site.
    This ultimately means adding 1 or 2 lines of code to certain files
   in the wp-includes folder.
 * The problem that I have is that they’ll most likely be overwritten when I update
   WordPress.
    So, **I’d like to know if there’s a way of making child templates
   for core files like there is for themes?** Or if my only option is to backup 
   my custom files before updating and restore them afterwards?
