Re: getting context's version

[Simon Pepping <spepping@scaprea.hobby.nl>]

This sounds like you want to make sure that you run a specific minimal
context version. In latex this may be checked by the macro code:

\NeedsTeXFormat{LaTeX2e}[1995/12/01]
\ProvidesClass{article}
              [2000/05/19 v1.4b
 Standard LaTeX document class]

and then when you say \documentclass{article}[2002/06/01], latex warns
you that you run an older version than required. This is a solution at
the root, so I think it is the way to go.
