# We do not use syntax allowed by C++11 standard

# We do not use conversion operators (int())

# We do not use assembler inlines

# We do not use "friends"

# Use references to objects rather than pointers, even for smart pointers.

# Group related classes to a single namespace

# If possible, avoid manual memory management (use of "new" and "delete" operators)

# If possible, avoid low-level thread management API ("pthread_xxx"), better to use boost or QT wrappers over it.
