When a mod is done to a single .php file which is located like say:
Do I need to copy the entire ..includes directory in my child theme directory?
OR can I just have an includes directory (to preserve the path?) and have only the file I want to mod. My first feeling is that this might confuse WP into thinking the includes folder ONLY contained that one file.
OR - can i just put the file.php in my child theme function.php and WP will magically find it?
And including the entire include directory seems... heavy-handed.
