+### number. Thus, FILE must be a source file, compiled into the
+### executable you are running. If omitted, FILE defaults to the
+### value of the global variable `srcfile'; most test scripts set
+### `srcfile' appropriately at the top anyway.
+###
+### Use this function to keep your test scripts independent of the
+### exact line numbering of the source file. Don't write:
+###
+### send_gdb "break 20"
+###
+### This means that if anyone ever edits your test's source file,
+### your test could break. Instead, put a comment like this on the
+### source file line you want to break at:
+###
+### /* breakpoint spot: frotz.exp: test name */
