Build Descriptor part

A build file (.eglbld extension) can contain multiple Build Descriptor parts. Each Build Descriptor part controls the generation process for a particular set of circumstances.
The Build Descriptor part contains the following information:
Build descriptor options
These options specify how to generate and prepare EGL output. A subset of the build descriptor options can cause other build parts to be included in the generation process. Some build descriptor options include settings that are stored as Java™ runtime properties.
Symbolic parameters
A symbolic parameter is a variable that affects the placement and preparation of generated output. Symbolic parameters are used only when you are generating COBOL.
Java runtime properties
The Java runtime properties set information that is included in a Java runtime properties file. You can specify properties that deal with database connections and date formats for available locales.
