Portability : portable
This module arranges the tokens of the module into different code
categories for HTML presentation. The parsed and typechecked module
categories for HTML presentation. The parsed and qualified module
is used to establish links between used identifiers and their definitions.
The fully qualified module is traversed to generate a list of code elements.
Code elements representing identifiers are distinguished by their kind
(type constructor, data constructor, function, (type) variable).
They include information about their usage (i.e., declaration, call etc.)
and whether the identifier occurs fully qualified in
the source code or not. Initially, all identifier codes are fully qualified.
In a next step, the token stream of the given program and the code list are
traversed sequentially (see `encodeToks`). The information in the token
stream is used to:
* add code elements for newlines, spaces and pragmas
* update the qualification information of identifiers in the code list.
