// Package plugin implements loading out-of-tree storage backends// using https://golang.org/pkg/plugin/ on Linux and macOS.//// If the $RCLONE_PLUGIN_PATH is present, any Go plugins in that dir// named like librcloneplugin_NAME.so will be loaded.//// To create a plugin, write the backend package like it was in-tree// but set the package name to "main". Then, build the plugin with////     go build -buildmode=plugin -o librcloneplugin_NAME.so//// where NAME equals the plugin's fs.RegInfo.Name.package plugin // Build for plugin for unsupported platforms to stop go complaining// about "no buildable Go source files".
