 Common styles
 =============
 
    There are several common styles of C code, including the GNU style,
 the Kernighan & Ritchie style, and the original Berkeley style.  A
 style may be selected with a single "background" option, which
 specifies a set of values for all other options.  However, explicitly
 specified options always override options implied by a background
 option.
 
    As of version 1.2, the default style of GNU `indent' is the GNU
 style.  Thus, it is no longer necessary to specify the option `-gnu' to
 obtain this format, although doing so will not cause an error.  Option
 settings which correspond to the GNU style are:
 
      -nbad -bap -nbc -bbo -bl -bli2 -bls -ncdb -nce -cp1 -cs -di2
      -ndj -nfc1 -nfca -hnl -i2 -ip5 -lp -pcs -nprs -psl -saf -sai
      -saw -nsc -nsob
 
    The GNU coding style is that preferred by the GNU project.  It is the
 style that the GNU Emacs C mode encourages and which is used in the C
 portions of GNU Emacs.  (People interested in writing programs for
 Project GNU should get a copy of `The GNU Coding Standards', which also
 covers semantic and portability issues such as memory usage, the size
 of integers, etc.)
 
    The Kernighan & Ritchie style is used throughout their well-known
 book `The C Programming Language'.  It is enabled with the `-kr'
 option.  The Kernighan & Ritchie style corresponds to the following set
 of options:
 
      -nbad -bap -bbo -nbc -br -brs -c33 -cd33 -ncdb -ce -ci4 -cli0
      -cp33 -cs -d0 -di1 -nfc1 -nfca -hnl -i4 -ip0 -l75 -lp -npcs
      -nprs -npsl -saf -sai -saw -nsc -nsob -nss
 
 Kernighan & Ritchie style does not put comments to the right of code in
 the same column at all times (nor does it use only one space to the
 right of the code), so for this style `indent' has arbitrarily chosen
 column 33.
 
    The style of the original Berkeley `indent' may be obtained by
 specifying `-orig' (or by specifying `--original', using the long
 option name).  This style is equivalent to the following settings:
 
      -nbad -nbap -bbo -bc -br -brs -c33 -cd33 -cdb -ce -ci4 -cli0
      -cp33 -di16 -fc1 -fca -hnl -i4 -ip4 -l75 -lp -npcs -nprs -psl
      -saf -sai -saw -sc -nsob -nss -ts8
