			===Check Code-Signing===

			To check whether the binary has been correctly signed, run the following command. If the binary has been successfully signed, this will not print anything out.

			<pre>
			$ codesign -v `which gdb`
	</pre>		</pre>

			=Installing=

			==Mac OS X==

			Install using homebrew:

			<pre>
			$ brew install gdb
			</pre>

			Then, you have to give gdb permission to control other processes:

			<pre>
			$ open /Applications/Utilities/Keychain\ Access.app
			</pre>

			Now create a new certificate for gdb by opening the menu item Keychain Access > Certificate Assistant > Create a Certificate

			Call it something like <code>gdb-cert</code>

			Set Identity Type to Self-Signed Root

			Set Certificate Type to Code Signing

			Select the "Let me override defaults" option

			Most of the other settings can remain the default

			Specify the location for the certificate to System (not login)

	{~~{Stub}~~}		=Simple Disassembly Example=

			Starting with a simple hello world program:

			<pre>
			#include <stdio.h>

			int main(void)
			{
			printf("Hello world! This is C.\n");
			return 0;
			}
			</pre>

			Now compile the program with debug flags:

			<pre>
			$ gcc -g hello_world.c -o hello_from_c.x
			</pre>

			and load it up into gdb:

			<pre>
			$ gdb hello_from_c.x
			</pre>

			Now you can run the program like normal:

			<pre>
			(gdb) run
			</pre>

			and to disassemble the binary into its assembly level instructions,

			<pre>
			(gdb) disassemble main
			</pre>
