 2.2 Headlines
 =============
 
 Headlines define the structure of an outline tree.  The headlines in Org
 start with one or more stars, on the left margin(1) (2).  For example:
 
      * Top level headline
      ** Second level
      *** 3rd level
          some text
      *** 3rd level
          more text
 
      * Another top level headline
 
 Some people find the many stars too noisy and would prefer an outline
 that has whitespace followed by a single star as headline starters.
 SeeClean view, describes a setup to realize this.
 
    An empty line after the end of a subtree is considered part of it and
 will be hidden when the subtree is folded.  However, if you leave at
 least two empty lines, one empty line will remain visible after folding
 the subtree, in order to structure the collapsed view.  See the variable
 ‘org-cycle-separator-lines’ to modify this behavior.
