"  vim: set sw=3 sts=3:

" Awk indent script. It can handle multi-line statements and expressions.
" It works up to the point where the distinction between correct/incorrect
" and personal taste gets fuzzy. Drop me an e-mail for bug reports and
" reasonable style suggestions.
"
" Bugs:
" =====
" - Some syntax errors may cause erratic indentation.
" - Same for very unusual but syntacticly correct use of { }
" - In some cases it's confused by the use of ( and { in strings constants
" - This version likes the closing brace of a multiline pattern-action be on
"   character position 1 before the following pattern-action combination is
"   formatted

" Author:

" History:
" ========
" 26-04-2002 Got initial version working reasonably well
" 29-04-2002 Fixed problems in function headers and max line width
"	     Added support for two-line if's without curly braces
" Fixed hang: 2011 Aug 31

" Only load this indent file when no other was loaded.
