+
+Code indentation
+----------------------------------------------------------------------
+Our C source code generally adheres to some basic code-formatting
+conventions. The existing code base is not totally consistent on this
+front, but we do prefer that contributed code be formatted similarly.
+In short, use spaces-not-TABs for indentation, use 2 spaces for each
+indentation level, and other than that, follow the K&R style.
+
+If you use Emacs, add the following to one of one of your start-up files
+(e.g., ~/.emacs), to help ensure that you get indentation right:
+
+ ;;; In libguestfs, indent with spaces everywhere (not TABs).
+ ;;; Exceptions: Makefile and ChangeLog modes.
+ (add-hook 'find-file-hook
+ '(lambda () (if (and buffer-file-name
+ (string-match "/libguestfs\\>" (buffer-file-name))
+ (not (string-equal mode-name "Change Log"))
+ (not (string-equal mode-name "Makefile")))
+ (setq indent-tabs-mode nil))))
+
+ ;;; When editing C sources in libguestfs, use this style.
+ (defun libguestfs-c-mode ()
+ "C mode with adjusted defaults for use with libguestfs."
+ (interactive)
+ (c-set-style "K&R")
+ (setq c-indent-level 2)
+ (setq c-basic-offset 2))
+ (add-hook 'c-mode-hook
+ '(lambda () (if (string-match "/libguestfs\\>" (buffer-file-name))
+ (libguestfs-c-mode))))

+ available as a separate upstream project.
+
+images/
+ Some guest images to test against. These are gzipped to save
+ space. You have to unzip them before use.

+
+Debugging
+----------------------------------------------------------------------
+
+It's a good idea to use guestfish to try out new commands.
+
+Debugging the daemon is a problem because it runs inside a minimal
+qemu environment. However you can print messages from the daemon, and
+they will show up if you use 'guestfish -v'.
