Source Code Documentation

The newer parts of strongSwan use extractable inline documentation extensively. This documentation is extracted with doxygen three times a day and uploaded to the /apidoc folder.

Code style

For new code (charon, libstrongswan, ...) we heavily use an object oriented programming style for C.
