+ % THIS IS A LATEX2E CLASS FILE; it will not work with LaTeX 2.09
+ % This is AGU++, an extension to the AGU official package AGUTeX
+ % It fixes up some problems with AGUTeX, adds many extra features
+ %  including putting figures, plates, tables in the text,
+ %  decent author-year citations and BibTeX support,
+ %  \title, \author, \affil allowed in preamble,
+ %  supplemental abstract for JGR,
+ %  balanced columns on last preprint page,
+ %  sublabelling of counters figure, plate, table, equation.
+ %
+ %  This package MUST be used in conjunction with one of the AGUTeX packages,
+ %  (version 4.0 or earlier)
+ %  which are given as options to the class, as for example:
+ %  \documentclass[agupp]{aguplus}
+ %  Other possible AGUTeX packages are: agums, agupp, jgrga, grlga, tecga,
+ %                                      radga, rtjga, paleo
+ %
+ %  See the manual AGUPLUS.TEX for details.

+ % THIS IS A LATEX 2.09 STYLE OPTION; it will not work with LaTeX2e
+ %     except in compatibility mode
+ % This is AGU++, an extension to the AGU official package AGUTeX
+ % It fixes up some problems with AGUTeX, adds many extra features
+ %  including putting figures, plates, tables in the text,
+ %  decent author-year citations and BibTeX support,
+ %  \title, \author, \affil allowed in preamble,
+ %  supplemental abstract for JGR,
+ %  balanced columns on last preprint page,
+ %  sublabelling of counters figure, plate, table, equation.
+ %
+ %  This package MUST be used in conjunction with one of the AGUTeX packages,
+ %  (version 4.0 or earlier)
+ %    and must follow it, as for example:
+ %  \documentstyle[agupp,aguplus]{article}
+ %  Other possible AGUTeX packages are: agums, agupp, jgrga, grlga, tecga,
+ %                                      radga, rtjga, paleo
