This directory contains source for the documentation. It is also the build target for doxygen output.

Directory Layout

. (Docs root)

High level content and format files. (E.g. css, header, footer.)

./Conceptual

Conceptual (non-api) documentation such as overviews, how-to's, etc.
The main index page content is also in this directory.

./Extern

API documentation that is located outside the source files.

When the API documentation gets too big or complex for the header
and source files, it goes in this directory.

./Images

Images related to the documentation.

./html

The target for the Doxygen build.  (Created during the build process.)

Miscellany

One of the requirements for the API documentation is that it has the minimum possible impact on the declarations in the header files. So, in general, the header file declarations only contain summary documentation. The detail documentation is placed as follows:

1. If an element is defined in a cpp file, then place the detail documentation in the source file.
2. If an element does not have an associated cpp file, then place the detail documentation at the end of the header file.
3. If there is a lot of detail documentation cluttering up the end of a header file, then the content is moved to a separate file in the Extern directory.

Building the Documentation

1. Download and install the appropriate Doxygen version. (See the first line in the Doxyfile for the current version.)
2. Run "doxygen" in the project root directory. (The location of the Doxyfile.) No arguments are required.

The generated html files will be located in the /Docs/html directory.

If you want to "version" the documentation, you can set the PROJECT_NUMBER setting in the Doxyfile. E.g. PROJECT_NUMBER = "(2014-04-23)". The project number will be added to the header of the documentation.
E.g. "Recast Navigation (2014-04-23)"
