I have an existing source-tree, with a bunch of subdirectories and thousands of source files. I have a new source-tree where some of the files have been updated and some new files/directories added.
The existing source-tree has a bunch of hidden subdirectories (.git) which the new source-tree lacks.
I'm looking for a way for all the updated and new files to find their way from the new source-tree to the existing. I don't mind for the similar files to be copied as well because it would have no adverse effect.
