55
56     <para>The <filename>/etc/locale.conf</filename> file configures
57     system-wide locale settings. It is read at early-boot by
58     <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para>
59
60     <para>The basic file format of <filename>locale.conf</filename> is
61     a newline-separated list of environment-like shell-compatible
62     variable assignments. It is possible to source the configuration
63     from shell scripts, however, beyond mere variable assignments, no
64     shell features are supported, allowing applications to read the
65     file without implementing a shell compatible execution
66     engine.</para>

84
85     <para>The locale settings configured in

88     individual programs or individual users.</para>
89
90     <para>Depending on the operating system, other configuration files
