+## This script converts an Ada file (and its dependency files) to Html.
+## Keywords, comments and strings are color-hilighted. If the cross-referencing
+## information provided by Gnat (when not using the -gnatx switch) is found,
+## the html files will also have some cross-referencing features, i.e. if you
+## click on a type, its declaration will be displayed.
+##
+## To find more about the switches provided by this script, please use the
+## following command :
+## perl gnathtml.pl -h
+## You may also change the first line of this script to indicates where Perl is
+## installed on your machine, so that you can just type
+## gnathtml.pl -h
+##
+## Unless you supply another directory with the -odir switch, the html files
+## will be saved saved in a html subdirectory
