 Roughly, Asterisk code formatting guidelines are generally equivalent to the 
 following:
 
-# indent -i4 -ts4 -br -brs -cdw -cli0 -ce -nbfda -npcs -npsl foo.c
+# indent -i4 -ts4 -br -brs -cdw -cli0 -ce -nbfda -npcs -nprs -npsl -saf -sai -saw foo.c
+
+this means in verbose:
+ -i4:    indent level 4
+ -ts4:   tab size 4
+ -br:    braces on if line
+ -brs:   braces on struct decl line
+ -cdw:   cuddle do while
+ -cli0:  case indentation 0
+ -ce:    cuddle else
+ -nbfda: dont break function decl args
+ -npcs:  no space after function call names
+ -nprs:  no space after parentheses
+ -npsl:  dont break procedure type
+ -saf:   space after for
+ -sai:   space after if
+ -saw:   space after while
 
 Function calls and arguments should be spaced in a consistent way across
 the codebase.
