package main

/*
Example Go program with multiple .NET Binaries embedded

This requires packr (https://github.com/gobuffalo/packr) and the utility. Install with:
	$ go get -u github.com/gobuffalo/packr/packr

Place all your EXEs are in a "binaries" folder

Run "packr build". The resulting Go binary will contain all the binaries embedded
