refer is a program for managing bibliographic references, and citing them in troff documents. It is implemented as a troff preprocessor.
refer was written by Mike E. Lesk at Bell Laboratories in or before 1978, and is now available as part of most Unix-like operating systems. A free reimplementation exists as part of the groff package.
The author then can refer to it in her troff document by listing keywords which uniquely match this reference:.[ kernighan cherry eqn .]
refer sees little use today, primarily because troff itself is not used much for longer technical writing that might need software support for reference and citation management.
Famous quotes containing the word refer:
“When we interpret nature, we refer phenomena that are rarely entirely unintelligible back to something that actually exists, but is equally unintelligible.”
—Franz Grillparzer (17911872)
