Editing Code folding (section)

===Collapsing comments===
Comments are a form of human-readable metadata, and lengthy comments can disrupt the flow of code. This can be the case either for a long comment for a short section of code, such as a paragraph to explain one line, or comments for [[documentation generator]]s, such as [[Javadoc]] or [http://msdn.microsoft.com/en-us/library/b2s063f7.aspx XML Documentation]. Code folding allows one to have long comments, but to display them only when required. In cases where a long comment has a single summary line, such as Python docstrings, the summary can still be displayed when the section is collapsed, allowing a summary/detailed view.
