groff: Macro Package Intro

 
 1.4 Macro Packages
 ==================
 
 Since 'groff' provides such low-level facilities, it can be quite
 difficult to use by itself.  However, 'groff' provides a "macro"
 facility to specify how certain routine operations (e.g. starting
 paragraphs, printing headers and footers, etc.) should be done.  These
 macros can be collected together into a "macro package".  There are a
 number of macro packages available; the most common (and the ones
 described in this manual) are 'man', 'mdoc', 'me', 'ms', and 'mm'.
