groff: Paragraphs in ms

 
 4.3.5.1 Paragraphs
 ..................
 
 The following paragraph types are available.
 
  -- Macro: .PP
      Sets a paragraph with an initial indentation.
 
  -- Macro: .LP
      Sets a paragraph without an initial indentation.
 
  -- Macro: .QP
      Sets a paragraph that is indented at both left and right margins.
      The effect is identical to the HTML '<BLOCKQUOTE>' element.  The
      next paragraph or heading returns margins to normal.
 
  -- Macro: .XP
      Sets a paragraph whose lines are indented, except for the first
      line.  This is a Berkeley extension.
 
    The following markup uses all four paragraph macros.

      .LP
      The following software and versions were
      considered for this report.
      .PP
      For commercial software, we chose
      .B "Microsoft Word for Windows" ,
      starting with version 1.0 through the
      current version (Word 2000).
      .PP
      For free software, we chose
      .B Emacs ,
      from its first appearance as a standalone
      editor through the current version (v20).
      See [Bloggs 2002] for details.
      .QP
      Franklin's Law applied to software:
      software expands to outgrow both
      RAM and disk space over time.
      .LP
      Bibliography:
      .XP
      Bloggs, Joseph R.,
      .I "Everyone's a Critic" ,
      Underground Press, March 2002.
      A definitive work that answers all questions
      and criticisms about the quality and usability of
      free software.
 
    The 'PORPHANS' register (Seems Document Control Registers)
 operates in conjunction with each of these macros, to inhibit the
 printing of orphan lines at the bottom of any page.
