<P> Sometimes source code contains a novel or noteworthy solution to a specific problem . In such cases, comments may contain an explanation of the methodology . Such explanations may include diagrams and formal mathematical proofs . This may constitute explanation of the code, rather than a clarification of its intent; but others tasked with maintaining the code base may find such explanation crucial . This might especially be true in the case of highly specialized problem domains; or rarely used optimizations, constructs or function - calls . </P> <P> For example, a programmer may add a comment to explain why an insertion sort was chosen instead of a quicksort, as the former is, in theory, slower than the latter . This could be written as follows: </P> <P> Logos, diagrams, and flowcharts consisting of ASCII art constructions can be inserted into source code formatted as a comment . Further, copyright notices can be embedded within source code as comments . Binary data may also be encoded in comments through a process known as binary - to - text encoding, although such practice is uncommon and typically relegated to external resource files . </P> <P> The following code fragment is a simple ASCII diagram depicting the process flow for a system administration script contained in a Windows Script File running under Windows Script Host . Although a section marking the code appears as a comment, the diagram itself actually appears in an XML CDATA section, which is technically considered distinct from comments, but can serve similar purposes . </P>
