51. Software versions

51.1. Introduction

.intro: This is the design of the support in the MPS for describing and inspecting versions.

51.2. Overview

.overview: There are three different sorts of version under consideration:

1. versions of the (MPS) library used (linked with);

2. versions of the interface used (header files in C) when compiling the client’s program; and

3. versions of the documentation used when the client was writing the program.

There are issues of programmatic and human access to these versions.

.overview.split: The design is split accordingly. See design.mps.version-library for the design of a system for determining the version of the library one is using. And other non-existent documents for the others.
