[packagekit] PackageKit frontend documentation

[Sveta Anisimova]

Hi,

I am working on linux autoupdate system implementation for large 
institutional labs. One of the options would be to use PackageKit 
system backends with a modified frontend functionality. References to 
any documentation online which give an overview of methods
and functions used for rewriting PackageKit frontend are really 
appreciated and would be of great help.

Many thanks in advance.
