The principal customisations for Fortran documents are to do with the definition of `short references' for certain tags, to help you `hide' SGML within Fortran comments.
The string *+ coming at the beginning of the line, is
equivalent to the func start-tag, and *- at the
beginning of the line is recognised as the codebody start-tag.
Within the func element, a * at the beginning of the
line is ignored. Further, within the parameter element, an
equals sign, =, is recognised as a type start-tag, and
within that element, end-of-line and : are recognised as a
description start-tag.
All together, this means that, as trailed in Section 5.1.1, the code fragment
*+
* <routinename>helloworld
* <description>Greets the world with a sunny hello
* <returnvalue type=string>Suitably formatted greeting
* <parameter given>
* language = enumerated list
* Selects the language to use.
* Allowed values are english and sanskrit.
* <authorlist><authorref id=ng>
