+ * tal/grab_file - file helper routines
+ *
+ * This contains simple functions for getting the contents of a file.
+ *
+ * Example:
+ *     #include <err.h>
+ *     #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;
+ *     }
