title: Is there a specification for a man page's SYNOPSIS section?
body: <p>I'm trying to write some specifications to be shared between a small team and getting picky about the format I put some command listings in. Is there any <em>formal</em> definition of the syntax used in the SYNOPSIS section of man pages?</p>
  
  <p>From the Wikimedia Commons, here's an example of a man page with the SYNOPSIS section I'm talking about, where the command is listed with the required and optional arguments it understands.</p>
