<!-- Wanted to avoid copying .css to each folder, so copied default .css from doxyen in here, kicked out most stuff we don't need for examples and modified some a little bit.
|
||
|
|
Target was having a single html in each example folder which is created from the main.cpp files and needs no files besides some images below media folder.
|
||
|
|
Feel free to improve :)
