| * Note: from the user's point of view, the characteristic function of this |
| * set of options is indistinguishable from that of the BuildRequestOptions: |
| * they are all per-request. The difference is only apparent in the |
| * implementation: these options are used only by the lib.exec machinery, which |
| * affects how C++ and Java compilation occur. (The BuildRequestOptions |
| * contain a mixture of "semantic" options affecting the choice of targets to |
| * build, and "non-semantic" options affecting the lib.actions machinery.) |
| * Ideally, the user would be unaware of the difference. For now, the usage |
