	\class BAppFileInfo
	\ingroup storage
	\ingroup libbe
	\brief Provides access to the metadata associated with executables,
		   libraries and add-ons.

	The BAppFileInfo class allows for information about an executable or
	add-on to be accessed or set. Information about an executable that can be
	accessed include the signature, catalog entry, supported MIME types,
	application flags, icon(s), and version info.

	You should initialize the BAppFileInfo with a BFile object that represents
	the executable or add-on that you want to access. If you only want to read
	metadata from the file you do not have to open it for reading. However, if
	you also want to write metadata then you should open the BFile for writing.

	To associate a BFile with a BAppFileInfo object you can either pass the
	BFile object into the constructor or you can use the empty constructor and
	then use the SetTo() method to set the BFile to the BAppFileInfo object.

	When accessing information from a BFileInfo object it will first look in the
	attributes of the BFile. If the information is not found then the BFileInfo
	object will next look at the resource of the BFile. You can tell the
	BFileInfo object to look only in the attributes or resources with the
	SetInfoLocation() method.
