// 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.
