10.2 Coding style

If you plan to contribute code to the Gmsh project, here are some easy rules to make the code easy to read/debug/maintain:

1. please enable full warnings for your compiler (e.g., add -Wall to FLAGS in the ‘variables’ file);
2. always use the Msg() function to print information, errors, …;
3. indent your files using ‘utils/misc/indent.sh’;
