        Web Pages  The html version of the GrADS 
        documentation has become the standard base documentation for GrADS. Follow 
        the links below to the Users Guide, an introductory tutorial session, 
        and an alphabetical subject index. Note the documentation is covered under 
        the same copyright as the GrADS source code.  The Users GuideThe Users Guide is the fundamental document that 
        provides information about how to use GrADS. The four main chapters are 
        General Topics, Analysis Topics, Display Topics, and the GrADS Scripting 
        Language.
 Tutorial 
        The tutorial will give you a feeling for how to use the 
        basic capabilities of GrADS. This sample session takes about 30 minutes 
        to run through. It is highly recommended for new users.  (En Español.)
 IndexThe Index provides a quick and easy interface 
        for checking the syntax and usage of any GrADS command or function. Subject 
        headings from the User's Guide are also listed in the Index.
