"A Hypertext for Literate Programming"
"In this paper we descibe a hypertext presentation for the WEB system for
literate programming. The requirements for an environment for modern literate
programming are analyzed and the WEB hypertext system is proposed. Different
types of windows for displaying texts, indices and graphical representations
are discussed. All semantic links and operators using them are analyzed.
The proposed architecture of the WEB hypertext system includes a general
purpose relational database management system. Mapping between hypertext
queries and relational database queries is provided. The system allows the user
to define new hypertext operations by providing the corresponding SQL queries
for the underlying relational database. The descirbed system can be easily
extended by many other types of queries and applications."

"A hypertext system for literate C++ programming"
"A tool was presented that supports the documentation of C++ program
systems by providing a modern user interface and comfortable browsing
facilities.
The tool supports the concepts of literate programming and hypertext and
can also be used for documenting existing software systems.
We have been using the presented tool in various projects at our institute.
Its usefulness has been proven by a drastic reduction of necessary effort
to maintain software systems and avoid error-prone changes while maintaining
a software system."
