modified-since

Returns seq of regular files (non-directories, non-symlinks) from `file-set` that were modified since the `anchor` path. The `anchor` path can be a regular file or directory, in which case the recursive max last modified time stamp is used as the timestamp to compare with. The `file-set` may be a regular file, directory or collection of files (e.g. returned by glob). Directories are searched recursively.
