// into one we can't accurately remove a file not in one of the source directories.
// If a file is in the local static dir and also in the theme static dir and we remove
// it from one of those locations we expect it to still exist in the destination
// If a file is generated by the content over a static file we expect it to remain as well.
// Because we are never certain if the file was overwritten by the content generation
// We can't effectively remove anything.
//
// This leads to two approaches:
// 1. Not overwrite anything
// 2. Assume these cases are rare and overwrite anyway. If things get out of sync
// a clean sync will be needed.
// There is an alternative which is quite heavy. We would have to track every single file
// placed into the publishedPath and which pipeline put it there.
// We have chosen to take the 2nd approach
// If Hugo generates a file (from the content dir) over a static file
// the content generated file should take precedence.
//
// Because we are now watching and handling individual events it is possible that a static
// event that occupies the same path as a content generated file will take precedence
// until a regeneration of the content takes places.
//
// Hugo assumes that these cases are very rare and will permit this bad behavior
// The alternative is to track every single file and which pipeline rendered it
// and then to handle conflict resolution on every event.
