 Problems are written in xml markup, which can appear complex when you first start to work with LON-CAPA if you have not done html or other coding. However, each xml element has a starting and closing argument, just like html. This manual includes a reference on xml markup used to write problems.

+The authoring environment includes a `colorful' web-based editor that can be used for authoring your first problems. Even experts will
 often start with the colorful editor to build a template for a problem. It is possible to switch back and forth between the colorful editor and xml when composing and testing your problems. Often simple issues are easier to clean up directly in xml. Also, it is easier to copy/paste xml to 
 build additional problem sections compared to using the colorful editor.
 
 \textbf{Scripts}
 
-The power of LON-CAPA for problem randomization and computing randomized answers is realized through writing perl script at the top of a problem. Example scripts are included in many example problems, and most resource authors publish scripts with the problems, so many examples are available. Many special functions have been created to use in scripts. This manual includes a section on writing scripts.
