## 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
