SBK-GEM-YAL : YML Arguments Loader

Api

The SBK-GEM-YAL (YML Arguments Loader) is a wrapper for SBK-GEM. The SBK-GEM-YAL extracts arguments from the YML file and invokes the SBK-GEM command with the same arguments as command line parameters. you can store the SBK-GEM arguments in a YML file and can be given as input to SBK-GEM-YAL application/command. Use this example YML file sbk-gem.yml to build your own YML file for SBK-GEM-YAL command/application.

Build SBK-GEM-YAL

SBK-GEM-YAL is a submodule/project of the SBK framework. If you build SBK, it builds the SBK-GEM-YAL package too.
