<refsect1><title>Description</title>
<para><command>glib-compile-schemas</command> compiles all the GSettings XML
schema files in <replaceable>DIRECTORY</replaceable> into a binary file
with the name <filename>gschemas.compiled</filename> that can be used
by <link linkend="GSettings"><type>GSettings</type></link>. The XML schema
files must have the filename extension <filename>.gschema.xml</filename>.
For a detailed description of the XML file format, see the
<link linkend="GSettings"><type>GSettings</type></link> documentation.
</para>
<para>
At runtime, GSettings looks for schemas in the
<filename>glib-2.0/schemas</filename> subdirectories of all directories
specified in the <envar>XDG_DATA_DIRS</envar> environment variable. The
usual location to install schema files is
<filename>/usr/share/glib-2.0/schemas</filename>.
</para>
<para>
In addition to schema files, glib-compile-schemas reads 'vendor override'
files, which are key files that can override default values for keys in
the schemas. The group names in the key files are the schema id, and the
values are written in serialized GVariant form.
Vendor override files must have the filename extension
<filename>.gschema.override</filename>.
</para>
<para>
By convention, vendor override files begin with <filename>nn_</filename>
where <filename>nn</filename> is a number from 00 to 99.  Higher
numbered files have higher priority (eg: if the same override is made in
a file numbered 10 and then again in a file numbered 20, the override
from 20 will take precedence).
