-an installed extension with this work?" and "does any entry in the dictionary
-relate to this work?": there may be many extensions and very many dictionary
-entries, so we keep an incidence count of each work and in what context it
-has been used, and store that in a hash table. Note that each distinct work
-is recorded only once in the table: this is important, as although an
-individual extension can only be loaded or installed once, it could be
-referred to in the dictionary dozens or even hundreds of times.

-@h The database of known works.
-We will need to be able to give rapid answers to questions like "is there
-an installed extension with this work?" and "does any entry in the dictionary
-relate to this work?": there may be many extensions and very many dictionary
-entries, so we keep an incidence count of each work and in what context it
-has been used, and store that in a hash table. Note that each distinct work
-is recorded only once in the table: this is important, as although an
-individual extension can only be loaded or installed once, it could be
-referred to in the dictionary dozens or even hundreds of times.
-
-The table is unsorted and is intended for rapid searching. Typically there
-will be only a handful of works in the list of those with a given hash code:
-indeed, the typical number will be 0 or 1.
-
-Works are entered into the database with one of the following contexts:
