escape/delimiter —
escaping delimiters in macro arguments
  - [intermediate] Some programs, for example
      less(1),
      accept the question mark as a command line flag to display a brief help
      text. Write some
      mdoc(7)
      code to talk about this flag in the DESCRIPTION, for example:
    
    The -?option
      displays a summary of the commands.
 
- [advanced] Write a SYNOPSIS for the standard
      test(1)
      utility. This utility takes an expression
      as its argument. Do not try to express the expression syntax in the
      SYNOPSIS, just put the word expression
      there. The command name can be either test or
      a an opening square bracket. In the latter case, the final argument must
      be a closing square bracket.
  - See the “Delimiters” subsection in the
      mdoc(7)
      manual for help.
- The SYNOPSIS should consist of two lines.
