+### gdb_get_line_number TEXT [FILE]
+###
+### Search the source file FILE, and return the line number of a line
+### containing TEXT. Use this function instead of hard-coding line
+### numbers into your test script.
+###
+### Specifically, this function uses GDB's "search" command to search
+### FILE for the first line containing TEXT, and returns its line
+### 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 */
+###
+### and then write, in your test script (which we assume is named
+### frotz.exp):
+###
+### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n"
+###
+### (Yes, Tcl knows how to handle the nested quotes and brackets.
+### Try this:
+### $ tclsh
+### % puts "foo [lindex "bar baz" 1]"
+### foo baz
+### %
+### Tcl is quite clever, for a little stringy language.)
