-// @file LexPowerPro.cxx
-// PowerPro utility, written by Bruce Switzer, is available from http://powerpro.webeddie.com
-// PowerPro lexer is written by Christopher Bean (cbean@cb-software.net)
-//
-// Lexer code heavily borrowed from:
-// LexAU3.cxx by Jos van der Zande
-// LexCPP.cxx by Neil Hodgson
-// LexVB.cxx by Neil Hodgson
-//
-// Changes:
-// 2008-10-25 - Initial release
-// 2008-10-26 - Changed how <name> is hilighted in 'function <name>' so that
-// local isFunction = "" and local functions = "" don't get falsely highlighted
-// 2008-12-14 - Added bounds checking for szKeyword and szDo
-// - Replaced SetOfCharacters with CharacterSet
-// - Made sure that CharacterSet::Contains is passed only positive values
-// - Made sure that the return value of Accessor::SafeGetCharAt is positive before
-// passsing to functions that require positive values like isspacechar()
-// - Removed unused visibleChars processing from ColourisePowerProDoc()
-// - Fixed bug with folding logic where line continuations didn't end where
-// they were supposed to
-// - Moved all helper functions to the top of the file
