From c16e9f4ed97f65357e9986f46ad88ee9f2237997 Mon Sep 17 00:00:00 2001 From: Andras Timar Date: Fri, 15 Feb 2013 13:02:10 +0100 Subject: Move SyntaxHighlighter class from svtools to comphelper We use this class in helpcompiler, and it is not desirable to compile svtools (thus half of LibreOffice) for a build tool in cross-compiling environment.
