+ * grab_file - file helper routines
+ *
+ * This contains simple functions for getting the contents of a file.
+ *
+ * Example:
+ *     #include "grab_file/grab_file.h"
+ *     #include <err.h>
+ *     #include <stdio.h>
+ *     #include <string.h>
+ *
+ *     int main(int argc, char *argv[])
+ *     {
+ *             size_t len;
+ *             char *file;
+ *
+ *             file = grab_file(NULL, argv[1], &len);
+ *             if (!file)
+ *                     err(1, "Could not read file %s", argv[1]);
+ *             if (strlen(file) != len)
+ *                     printf("File contains NUL characters\n");
+ *             else if (len == 0)
+ *                     printf("File contains nothing\n");
+ *             else if (strchr(file, '\n'))
+ *                     printf("File contains multiple lines\n");
+ *             else
+ *                     printf("File contains one line\n");
+ *             talloc_free(file);
+ *
+ *             return 0;
