SUFFIXES(7)         Linux Programmer's Manual         SUFFIXES(7)

       suffixes - list of file suffixes

       It  is  customary  to indicate the contents of a file with
       the file suffix, which consists of a period,  followed  by
       one  or  more  letters.   Many standard utilities, such as
       compilers, use this to recognize the type of file they are
       dealing  with.   The  make(1)  utility  is driven by rules
       based on file suffix.

       Following is a list of suffixes which  are  likely  to  be
       found on a Linux system.
