-###
-### Search the source file FILE, and return the line number of a 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.)

+# The previous implementation of this procedure used the gdb search command.
+# This version is different:
+#
+# . It works with MI, and it also works when gdb is not running.
+#
+# . It operates on the build machine, not the host machine.
+#
+# . For now, this implementation fakes a current directory of
+# $srcdir/$subdir to be compatible with the old implementation.
+# This will go away eventually and some callers will need to
+# be changed.
+#
+# . The TEXT argument is literal text and matches literally,
+# not a regular expression as it was before.
+#
+# . State changes in gdb, such as changing the current file
+# and setting $_, no longer happen.
+#
+# After a bit of time we can forget about the differences from the
+# old implementation.
