+be closed implicitly when its reference count goes to zero (eg.
+when it goes out of scope or the program ends). This call is
+only required in some exceptional cases, such as where the program
+may contain cached references to the handle 'somewhere' and you
+really have to have the close happen right away. After calling
+C<close> the program must not call any method (including C<close>)

+
+From time to time we add new libguestfs APIs. Also some libguestfs
+APIs won't be available in all builds of libguestfs (the Fedora
+build is full-featured, but other builds may disable features).
+How do you test whether the APIs that your Perl program needs are
+available in the version of C<Sys::Guestfs> that you are using?
+
+To test if a particular function is available in the C<Sys::Guestfs>
+class, use the ordinary Perl UNIVERSAL method C<can(METHOD)>
+(see L<perlobj(1)>). For example:
+
+ use Sys::Guestfs;
+ if (defined (Sys::Guestfs->can (\"set_verbose\"))) {
+ print \"\\$h->set_verbose is available\\n\";
+ }
+
+To test if particular features are supported by the current
+build, use the L</available> method like the example below. Note
+that the appliance must be launched first.
+
+ $h->available ( [\"augeas\"] );
+
+Since the L</available> method croaks if the feature is not supported,
+you might also want to wrap this in an eval and return a boolean.
+In fact this has already been done for you: use
+L<Sys::Guestfs::Lib(3)/feature_available>.
+
+For further discussion on this topic, refer to
+L<guestfs(3)/AVAILABILITY>.

The guestfs module provides a Python binding to the libguestfs API
Libguestfs provides ways to enumerate guest storage (eg. partitions,
LVs, what filesystem is in each LV, etc.). It can also run commands
-in the context of the guest. Also you can access filesystems over FTP.
+in the context of the guest. Also you can access filesystems over

Errors which happen while using the API are turned into Python
RuntimeError exceptions.

+//
+// The second issue is that some calls are known to be incorrect and

+// return string[], or return any structure value. This is because
+// we haven't worked out the correct way to do this from C#.
+//
+// The third issue is that when compiling you get a lot of warnings.
+// We are not sure whether the warnings are important or not.
+//
+// Fourthly we do not routinely build or test these bindings as part
+// of the make && make check cycle, which means that regressions might
+// go unnoticed.
+//
+// Suggestions and patches are welcome.
+
+// To compile:
+//
+// gmcs Libguestfs.cs
+// mono Libguestfs.exe

+// otherwise this won't do anything useful).
