[wp-hackers] Best practices for hunting depreciated functions.

When I'm developing new plugins I run a full mirror of my sites on a localhost to test the plugin across multiple datasets and structures, but the secondary benefit is that I can use the cross file search capacity of my editor to quickly do a bulk search across thousands of files.
I'm 100% sure that you're right, there must be a better way to handle this and I'd love to know how but for me, the fastest way to detect depreciated functions is oddly similar to your own.
