" Vim syntax file
" Language: CP2K input files
" Maintainer: based on work by Alin M Elena available at https://gitorious.org/cp2k-vim
" Revision: 13th of September 2010
" History:
" - XSLT dump and improved syntax highlighting (10.12.2013, Matthias Krack)
" - Folding and automatic indentation added (13.12.2013, Matthias Krack)
" - Remove folding since it overrides user's defaults (18.11.2016, Patrick Seewald)
