Package sequential provides a set of functions for managing sequential files on Windows. The origin of these functions are the golang OS and windows packages, slightly modified to only cope with files, not directories due to the specific use case. The alteration is to allow a file on Windows to be opened with FILE_FLAG_SEQUENTIAL_SCAN (particular for docker load), to avoid eating the standby list, particularly when accessing large files such as layer.tar. For non-Windows platforms, the package provides wrappers for the equivalents in the os packages. They are passthrough on Unix platforms, and only relevant on Windows.
