-// Package wails implements Go bindings to https://github.com/zserge/webview C library.
-// It is a modified version of webview.go from that repository
-
-// Bindings closely repeat the C APIs and include both, a simplified
-// single-function API to just open a full-screen webview window, and a more
-// advanced and featureful set of APIs, including Go-to-JavaScript bindings.
-//
-// The library uses gtk-webkit, Cocoa/Webkit and MSHTML (IE8..11) as a browser
-// engine and supports Linux, MacOS and Windows 7..10 respectively.
