 * This manager is used to register and create the services that are used
41 
 * to manage the plugin installers. The services that offers are basically
42 
 * two: the creation of installers service and the execution of installers
41 
 * to manage the creation and the execution of installers. An installer is
42 
 * a file called <b>bundle</b> that is composed of a set <b>packages</b>.
43 
 * </p>
44 
 * <p>
45 
 * A package has some information that is defined by the {@link PackageInfo}
46 
 * class and is composed of a set of attributes. One of these attributes,
47 
 * the type, denotes if the package is a plugin, theme, translation, etc.

 * In practice a bundle is just a compressed zip file that has a compressed zip file
51 
 * for every package to install. The structure of a bundle file with two
52 
 * packages of type plugin could be:
53 
 * </p>
54 
 * <pre>
55 
 * - bundle (compressed file)
56 
 * 		- org.gvsig.plugin1-1_0_0-23 (compressed file)
57 
 * 			- org.gvsig.plugin1
58 
 * 			  	- package.info
59 
 *  	- org.gvsig.plugin2-2_0_1-35 (compressed file)
60 
 *  		- org.gvsig.plugin1
61 
 *  			- package.info
62 
 * </pre>
63 
 * <p>
64 
 * bundle is the compressed file that contains a zip entry for every
65 
 * package to install. The name of the zip entry follows next pattern:
66 
 * </p>
67 
 * <pre>
68 
 * 		[package code]-[version]-[build]
69 
 * </pre>
70 
 * <p>
71 
 * Every zip entry contains a main folder inside that contains all the
72 
 * package files that are used in the installation process. Depending of the
73 
 * type of packages, the information inside this folder can be different,
74 
 * but all the types of packages have to have the <b>package.info</b> that
75 
 * has all the package information. To see the <b>package.info</b> description
76 
 * see {@link PackageInfo}.
77

 * The services that offers this managers are basically two: the creation of
80 
 * bundles for just one package of type plugin and a service for the
81 
 * installation of packages.
