+Easily create HTTP endpoints (hooks) to execute shell commands
+
+webhook is a lightweight configurable tool written in Go, that allows you to
+easily create HTTP endpoints (hooks) on your server, which you can use to
+execute configured commands.  You can also pass data from the HTTP request
+(such as headers, payload or query variables) to your commands.  webhook
+also allows you to specify rules which have to be satisfied in order for the
+hook to be triggered.
