 <strong>Include guards:</strong> all headers must have include guards to prevents name conflict. These are place right after the license and at the end of the file. The adopted format includes the relative path in ADIOS. For example, **adios2/engine/bp/BPFileWriter.h**  will contain the following include guards:<ol><li><ul><li><pre style="border: 0;"><code>#ifndef  ADIOS2_ENGINE_BP_BPFILEWRITER_H_
  #define  ADIOS2_ENGINE_BP_BPFILEWRITER_H_<br><br>
