2<h2>List of GSAS-II tutorials</H2><UL>
3
4    <p> A list of available tutorials appears below. Each tutorial is a
5    web page that can be opened using the link below, but most tutorials also need
6    to have example data files downloaded. This can also be done with links included below,
7    but it can be easier to access tutorials using
8    <b>Help/Tutorials</b> menu item.
9    When this menu entry is used from inside GSAS-II (unless "browse tutorial on web" is selected),
10    the data files are downloaded to a local directory and GSAS-II will start from that directory
11    for most file open commands.
