Question: how to add new menu functionality

[Stephen Torri]

I am using the released grub-1.98 code for my development. The problem I
am having is how to add new functionality to the 'normal' module. I
would like to add a new feature to the code using some functions that
don't presently exist in the code. When I coded the functions I had to
manually edit def-normal.lst to get the compiler to be happy and
successfully complete the build. This was not enough because when used
the new grub2 loader on a drive I got an error saying "error: the symbol
'work' not found" is displayed. This error code is reported because the
symbol cannot be found in a symbol table. So to summarize what I am
asking:

1. How do you configure the build system to compile with new files (e.g.
new command for command line)?

2. How do you configure the build system to compile with new functions
contained in existing files?

3. Is there a tutorial on how to develop for Grub2? If I missed that in
my search I am sorry for not reading that first.

4. How do you debug your Grub2 builds? The web had references to a patch
to add in GDB functionality.
