<title>Running GIO applications</title>
<para>
GIO inspects a few of environment variables in addition to the
ones used by GLib.
</para>
<formalpara>
<title><envar>XDG_DATA_HOME</envar>, <envar>XDG_DATA_DIRS</envar></title>
<para>
GIO uses these environment variables to locate MIME information.
For more information, see the <ulink url="http://freedesktop.org/Standards/shared-mime-info-spec">Shared MIME-info Database</ulink>
and the <ulink url="http://freedesktop.org/Standards/basedir-spec">Base Directory Specification</ulink>.

<para>
The following environment variables are only useful for debugging
GIO itself or modules that it loads. They should not be set in a
production environment.
</para>
<formalpara>
<title><envar>GIO_USE_VFS</envar></title>
<para>
This environment variable can be set to the name of a #GVfs
implementation to override the default for debugging purposes.
The #GVfs implementation for local files that is included in GIO
has the name "local", the implementation in the gvfs module has
the name "gvfs".
</para>
</formalpara>
<formalpara>
<title><envar>GIO_USE_VOLUME_MONITOR</envar></title>
<para>
This variable can be set to the name of a #GVolumeMonitor
implementation to override the default for debugging purposes.
The #GVolumeMonitor implementation for local files that is included
in GIO has the name "unix", the hal-based implementation in the
gvfs module has the name "hal".
</para>
</formalpara>
<formalpara>
<title><envar>GVFS_INOTIFY_DIAG</envar></title>
<para>
When this environment variable is set and GIO has been built
with inotify support, a dump of diagnostic inotify information
will be written every 20 seconds to a file named
<filename>/tmp/gvfsdid.<replaceable>pid</replaceable></filename>.
