+=head2 guestfs_aug_close
+
+ int guestfs_aug_close (guestfs_h *handle);
+
+Close the current Augeas handle and free up any resources
+used by it. After calling this, you have to call
+C<guestfs_aug_init> again before you can use any other
+Augeas functions.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_aug_defnode
+
+ struct guestfs_int_bool *guestfs_aug_defnode (guestfs_h *handle,
+ const char *name,
+ const char *expr,
+ const char *val);
+
+Defines a variable C<name> whose value is the result of
+evaluating C<expr>.
+
+If C<expr> evaluates to an empty nodeset, a node is created,
+equivalent to calling C<guestfs_aug_set> C<expr>, C<value>.
+C<name> will be the nodeset containing that single node.
+
+On success this returns a pair containing the
+number of nodes in the nodeset, and a boolean flag
+if a node was created.
+
+This function returns a C<struct guestfs_int_bool *>.
+I<The caller must call C<guestfs_free_int_bool> after use>.
+
+=head2 guestfs_aug_defvar
+
+ int guestfs_aug_defvar (guestfs_h *handle,
+ const char *name,

+of evaluating C<expr>. If C<expr> is NULL, then C<name> is
+undefined.
+
+On success this returns the number of nodes in C<expr>, or
+C<0> if C<expr> evaluates to something which is not a nodeset.
+
+On error this function returns -1.
+
+=head2 guestfs_aug_get
+
+ char *guestfs_aug_get (guestfs_h *handle,

+Look up the value associated with C<path>. If C<path>
+matches exactly one node, the C<value> is returned.
+
+This function returns a string or NULL on error.
+I<The caller must free the returned string after use>.
+
+=head2 guestfs_aug_init
+
+ int guestfs_aug_init (guestfs_h *handle,

+guestfs session, then it is closed.
+
+You must call this before using any other C<guestfs_aug_*>
+commands.
+
+C<root> is the filesystem root. C<root> must not be NULL,
+use C</> instead.
+
+The flags are the same as the flags defined in
+E<lt>augeas.hE<gt>, the logical I<or> of the following
+integers:
+

+
+Make save a no-op, just record what would have been changed.
+
+=item C<AUG_NO_LOAD> = 32
+
+Do not load the tree in C<guestfs_aug_init>.
+
+=back
+
+To close the handle, you can call C<guestfs_aug_close>.

+flag C<before>).
+
+C<path> must match exactly one existing node in the tree, and
+C<label> must be a label, ie. not contain C</>, C<*> or end
+with a bracketed index C<[N]>.
+
+This function returns 0 on success or -1 on error.

+
+This function returns a NULL-terminated array of strings
+(like L<environ(3)>), or NULL if there was an error.
