+Package Manipulation:
+	update  		Update list of available packages

+	install <file.ipk>	Install package <file.ipk>
+	install <file.deb>	Install package <file.deb>
+	remove <pkg>		Remove package <pkg>
+
+Informational Commands:
+	list    		List available packages and descriptions
+	files <pkg>		List all files belonging to <pkg>
+	search <file>		Search for a packaging providing <file>
+	info [pkg [<field>]]	Display all/some info fields for <pkg> or all
+	status [pkg [<field>]]	Display all/some status fields for <pkg> or all
+	depends <pkg>		Print uninstalled package dependencies for <pkg>
+
+Options:
+	-d <dest_name>          Use <dest_name> as the the root directory for
+	-dest <dest_name>	package installation, removal, upgrading.
+				<dest_name> should be a defined dest name from the
+				configuration file, (but can also be a directory
+				name in a pinch).
+        -o <offline_root>       Use <offline_root> as the root for offline installation.
+        -offline <offline_root> 				
+
+Force Options (use when ipkg is too smart for its own good):
+	-force-depends          Make dependency checks warnings instead of errors
+	-force-defaults         Use default options for questions asked by ipkg.
+                                (no prompts). Note that this will not prevent
