In Dmitry's book [1] is a pretty good description of what should be set 
in ext_emconf.php.

The second one is the "modern" version. The single depends, conflicts, 
suggests are obsolete.
The constraints section allows you to set a lower and/or upper limit to 
the version (both optional). E.g.
'constraints' => array(
	'depends' => array (
		'ext_key' => '2.3.1-',		//version >= 2.3.1
		'ext_key4' => '-1.0.2',		//version < 1.0.2
	),
	'conflicts' => array(
		'ext_key2' => '',		//any version
	),
	'suggests' => array(
		'ext_key3' => '1.0.0-1.0.999',	//1.0.0 <= version <= 1.0.999
	),
),
