* This class encapsulates a single substitution variable.
* Such a variable has the following information:
* <ol>
* <li>The actual variable, as in "&L"
* <li>A translated description of the variable, as in "Library name"
* <li>A display string, which is typically a concatenation of the above two attributes
* </ol>
* Currently this class is not used at runtime to do the actual substitution,
* although that would be a natural next step.
