  41 suffixes \- list of file suffixes
  42 .SH DESCRIPTION
  43 It is customary to indicate the contents of a file with the file suffix,
  44 which consists of a period, followed by one or more letters.
  45 Many standard utilities, such as compilers, use this to recognize the type of
  46 file they are dealing with.
  47 The
  48 .BR make (1)
  49 utility is driven by rules based on file suffix.
