EGL automatically creates a build file for each project, using the name of the project plus the .eglbld file extension. The projectname _Java Build Descriptor part in this file is assigned by default to each of the EGL Default Build Descriptors for the project.
You can also specify EGL Default Build Descriptors for each generatable part, package, or subfolder. By default, these options are blank, which causes them to default to the values at the project level. EGL searches for a build descriptor at the part level and moves up the folder tree until a default build descriptor is assigned.
