//  TODO: Search Info[-macos](classic).plist dictionary in addition

//
//  Maybe try a brainstorm a way to change the wxMimeTypesManager API
//  to get info from a file instead/addition to current get all stuff
//  API so that we can use Launch Services to get MIME type info.
//
//  Implement GetIcon from one of the FinderInfo functions - or
//  use Launch Services and search that app's plist for the icon.
//
//  Put some special juice in for the print command.
//

// for compilers that support precompilation, includes "wx.h".
