39 * The Shell Light-Weight Api dll provides a large number of utility functions

41 * Internet Explorer as a free download, it became a core part of Windows when
42 * Internet Explorer was 'integrated' into the O/S with the release of Win98.
44 * All functions exported by ordinal are undocumented by MS. The vast majority
45 * of these are wrappers for Unicode functions that may not exist on early 16
46 * bit platforms. The remainder perform various small tasks and presumably were
47 * added to facilitate code reuse amongst the MS developers.
