\brief The QCompressedHelpInfo class provides access to
the details about a compressed help file.
The detailed information about the compressed
help file can be fetched by calling the fromCompressedHelpFile()
static method, providing the path to the compressed
help file.
The class provides access to various information about a compressed help file.
The namespace associated with the given compressed help file is
namespaceName(), the associated component name is component()
and version() provides version information.
