LSB Certification System is designed to support the process of certifying Linux applications and distributions against the LSB standard. It guides user through the steps needed for getting certified, indicates the current step for each product and provides explanations on what to do next. It also facilitates the certification process by performing auxillary tasks such as uploading test results or calculating the certification fee.
The Product Directory lists LSB certified products (both applications and distributions) from all vendors. It allows to view which distributions and applications were certified for compliance with different LSB versions. For some of them additional notes are provided (for example, when some distribution requires installing additional packages for being fully LSB compliant).
