文本写作：troff - The Text Processor for Typesetters

troff很古老。

"The great strength of troff is the flexibility of the basic language and its programmability -- it can be made to do almost any formatting task."

-- The UNIX Programming Environment, Brian W. Kernighan and Rob Pike

troff更像是一种编程语言。这和所谓的WYSIWYG(What You See Is What You Get)编辑器是很不一样的。

groff是troff的GNU版本。

“GUIs normally make it simple to accomplish simple actions and impossible to accomplish complex actions.”

-- Doug Gwyn (22/Jun/91 in comp.unix.wizards)
