Common Print Dialog Backends - Development files for backends.

 The Common Print Dialog Backends project provides a D-Bus interface
 so that the print dialogs of GUI applications and the communication
 with the print technologies (CUPS/IPP, cloud printing services, Save
 to File, ...) are put into separate executables to be separately
 exchangeable.
 .
 The print dialogs of the different GUI toolkits and applications
 (GTK, Qt, LibreOffice, ...) are the frontends and to communicate with
 the different print technologies they use common backends. This way
 one simply adds new backends for new print technologies and updates
 the backends for changes in the print technologies, and immediately
 all applications are up-to-date, without need of modifying the code
 of the GUI toolkits or applications.
 .
 This package contains the header files to develop print dialog
 backends using libcpdb.
