This is one of four parts of the GAP documentation, the others being the GAP Tutorial, a beginner's introduction to GAP, the GAP Reference Manual, which contains the official definitions of GAP, and Programming in GAP which also provides information for those who want to write their own GAP extensions.
Extending GAP explains how to create files and functions that will work together with mechanisms built in GAP.
This manual is divided into chapters. Each chapter is divided into sections, and within each section, important definitions are numbered. References therefore are triples.
The first chapters of this manual describe how to write documentation, how to interface packages and components, and roughly describes the style used for writing the library. This is followed by chapters that explain advanced programming techniques in GAP. Finally there are chapters (alas, at the moment there is only one due to a lack of manpower) that describe how internal functions work and how to interface ones own code to these internal functions.
Pages are numbered consecutively in each of the four manuals. For manual conventions, see Section Manual Conventions in the Reference Manual.
