<< How to use gdb-wrapper >>
A debuggee, a program to be debugged,  must be compiled like the following:
	mygcc/bin/gcc -g -pg2 foobar.c

Now, type "./gdb-wrapper.pl a.out" to start gdb-wrapper.pl 

Usually, you can use it as raw GDB, which supports completion,
command history, inline editing, and so on.

To use commands of gdb-wrapper, type Ctrl+v when a prompt of GDB,
"(gdb)", is displayed, then you will see a prompt of gdb-wrapper,
"(wrapper)".

Type "help<RET>" to get help messages about available commands.
We implements the following commands in this version:
	revwatch var_name [target]
		execute reverse watchpoint operation.
		var_name is an address of a target variable,
		like *0x80499ec.
		an optional argument, target, specifies how many steps
		we go back.

	mark
		save the position.

	disp
		diplay a list of marked positions.

	jump pos_num
		restart a debuggee and go to the specified position.
		pos_num is displayed using "disp" command.

	setpos timestamp [file:line]
		save an arbitrary position, whose timestamp is "timestamp"
		and whose flie:line is "file:line".
		NOTE: We do NOT implement a system to check a validity
		      of given arguments.  If invalid arguments given,
		      gdb-wrapper may not work.

	help
		print help messages.

	q
	quit
		quit gdb-wrapper.


<< When gdb-wrapper.pl is moved to other systems >>
Execute the last step of Build.sh, which creates gdb-wrapper.pl from
gdb-wrapper.in using mkwrapper.pl.  If you want to make it manually,
do the following.

1. correct the path of "perl" at line 1 of gdb-wrapper.pl.

2. correct the path of modules of perl, which appears in an argument
   of -I option of perl.  Specify a directory containing Expect.pm
   and IO directory.  If you have these modules in perl system area,
   skip this step.

3. correct the path of gdb like the following:
	my($gdb_path) = "/usr/bin/gdb";
