100A Locale is a set of information that most programs use for determining
101country and language specific settings. The locales and their data
102are part of the system library and can be found
103at <path>/usr/share/locale</path> on most systems. A locale name is generally
104named <c>ab_CD</c >where <c>ab</c> is your two (or three) letter
105language code (as specified in ISO-639) and <c>CD</c> is your two letter country
106code (as specified in ISO-3199).

96<p>
97The next step is to set the <c>LANG</c> shell variable, which
98is used by your shell and window manager (and some other
99applications). Valid values can be found in
100<path>/usr/share/locale</path> and generally take the form
101<c>ab_CD</c>, where <c>ab</c> is your two letter language code
102and <c>CD</c> is your two letter country code. The <c>_CD</c>
103is left off if your language is only (or primarily) spoken in
104one country. <c>LANG</c> can be set in
105<path>/etc/profile</path> if you want it to take effect
106system-wide, or in <path>~/.bashrc</path> as a user-specific
107setting.
108</p> 115<p>
116Locale settings are stored in environment variables. These are typically
117set in the <path>/etc/env.d/02locale</path> (for system-wide
118settings) and <path>~/.bashrc</path> (for user-specific settings) file.
119The variables controlling different aspects of locale settings
120are given in the table below, those with highest precedence (ie. those
121that override settings below them) are at the top of the table. All variables
122take one name of a locale in <c>ab_CD</c> format given above.

134 locales which will override any other setting.

189Most typically users only set the LANG variable and perhaps LC_CTYPE variable
190on user level by adding definitions to shells startup files defining
191the environment variable manually from command line:

203<p>
204For message based localization to work in programs that support it, you will
205probably need to have programs compiled with the <c>nls</c> (Native language
206support) USE flag set. Most of the programs using nls also need the gettext
207library to extract and use localized messages. Of course, Gentoo's Portage will
208automatically install it when needed.
