Instance protocol:

 applyTo: file

Applies this patch to the given collection. Makes no sanity checks on the contents of the collection - simply blindly applies the chunks and snippets to its argument.

 initChunks: c file1: f1 file2: f2

 invert

Causes this patch to invert itself; if previously it represented the changes from file1 to file2, after being sent #invert, it will represent the changes from file2 to file1. After inversion, calling #applyTo: on file2 will yield file1, rather than the other way around.
