* Examples
** UnveilCommands
UnveilCommands takes a slice of commands & unveils them one by one, it will
return an error if unveil fails at any step. "no such file or directory" error
is ignored because binaries are not placed in every PATH.

Default permission is "rx".

#+BEGIN_SRC go
package main

import "tildegit.org/andinus/lynx"

func main() {
	commands := []string{"cd", "ls", "rm"}

	err = lynx.UnveilCommands(commands)
	if err != nil {
		log.Fatal(err)
	}
}
#+END_SRC
** UnveilPaths / UnveilPathsStrict
UnveilPaths takes a map of path, permission & unveils them one by one, it will
return an error if unveil fails at any step. "no such file or directory" error
is ignored, if you want to get that error too then use UnveilPathsStrict.

#+BEGIN_SRC go
package main

import "tildegit.org/andinus/lynx"

func main() {
	paths := make(map[string]string)

	paths["/home"] = "r"
	paths["/dev/null"] = "rw"
	paths["/etc/examples"] = "rwc"
	paths["/root"] = "rwcx"

	err = lynx.UnveilPaths(paths)
	if err != nil {
		log.Fatal(err)
	}

	// This will return an error if the path doesn't exist.
	err = lynx.UnveilPathsStrict(paths)
	if err != nil {
		log.Fatal(err)
	}
}
