+ *	#include <stdio.h>
+ *	#include <string.h>
+ *	#include <ccan/tal/grab_file/grab_file.h>
+ *	#include <ccan/tal/tal.h> // for tal_free
+ *
+ *	int main(int argc, char *argv[])
+ *	{
+ *		char *file;
+ *
+ *		file = grab_file(NULL, argv[1]);
+ *		if (!file)
+ *			err(1, "Could not read file %s", argv[1]);
+ *		if (strlen(file)+1 != tal_count(file))
+ *			printf("File contains NUL characters\n");
+ *		else if (tal_count(file) == 1)
+ *			printf("File contains nothing\n");
+ *		else if (strchr(file, '\n'))
+ *			printf("File contains multiple lines\n");
+ *		else
+ *			printf("File contains one line\n");
+ *		tal_free(file);
+ *
+ *		return 0;
