`gnathtml' is a Perl script that allows Ada source files to be browsed using standard Web browsers. For installation information, see Installing gnathtml.
Ada reserved keywords are highlighted in a bold font and Ada comments in a blue font. Unless your program was compiled with the gcc `-gnatx' switch to suppress the generation of cross-referencing information, user defined variables and types will appear in a different color; you will be able to click on any identifier and go to its declaration.
