2. PDL Overview
PDL (Program Design Language) is for designing at a slightly higher level that the code itself.
Use English-like statements that precisely describe specific operations
Write PDL at the level of intent.
Write PDL at a low enough level that generating code from it will be nearly automatic.

3. PDL Benefits:
PDL makes reviews easier
PDL supports the idea of iterative refinement: architecture->interface & PDL->source code
PDL makes changes easier
PDL minimizes commenting effort
PDL will be turned into comments for source code
PDL is easier to maintain that other forms of design documentation.
