  20 .SH NAME
  21 suffixes \- list of file suffixes
  22 .SH DESCRIPTION
  23 It is customary to indicate the contents of a file with the file suffix,
  24 which (typically) consists of a period, followed by one or more letters.
  25 Many standard utilities, such as compilers, use this to recognize the type of
  26 file they are dealing with.
  27 The
  28 .BR make (1)
  29 utility is driven by rules based on file suffix.

  31 Following is a list of suffixes which are likely to be found on a
