=== arabicThis is an example environment for typesetting Arabic documents in Mark IV (ConTeXt with LuaTeX). It won't work at all in Mark II (with either pdfTeX or XeTeX).tex ===

To use a specific font just put Save it under the current directory where you run context, as "ara-sty.tex" and replace ScheherazadeRegOT with use "\environment ara-sty" in your font file name. Then run 'context arabic.tex' document.
