Some of these things are possible (like using variables, etc).  Other
things are not possible yet.  One of the most import (at least for
you!) missing constructs is the `for' which can be used to iterate
over files in bash.

I noticed you mention hda1 here, which is a Linux device name.  I have
explained you before it is technically not possible to translate GRUB
device names to Linux device names.  I wish it was possible, but
unfortunately it currently isn't because the BIOS is used to access
harddisks.

Here are some things I would like to work on:

- Error handling.  It should become very clear how errors are dealt
  with from scripts.

- The `for' loop.  This is useful in some cases, for example to
  automatically include files, to generate menu entries, etc, etc.

- Generating menu entries.  My plan is to make it possible to create
  templates over which you can iterate.  I will explain this another
  time in detail.

- Completing/rewriting the test command (which I almost finished, btw).

- Documentation.  This is the most important thing that is currently
  lacking.  I will soon write a document that describes the current
  functionality and the functionality I plan to implement.  This is
  important for people who like to test all this, but more
  importantly: it gives fellow developers the chance to influence what
  I am doing, criticize it and to take part in the discussion about
  the syntax.

- Adding random features and bug fixing.

The documentation will come within a few weeks (or days, who
knows...).  It's important to me and other people that these features
can and will be discussed.
