11 This is the Tango I18N gateway, which extends the basic Layout
12 module with support for cuture- and region-specific formatting
13 of numerics, date, time, and currency.
14
15 Use as a standalone formatter in the same manner as Layout, or
16 combine with other entities such as Stdout. To enable a French
17 Stdout, do the following:
18 ---
19 Stdout.layout = new Locale (Culture.getCulture ("fr-FR"));
20 ---
21
22 Note that Stdout is a shared entity, so every usage of it will
23 be affected by the above example. For applications supporting
24 multiple regions create multiple Locale instances instead, and
25 cache them in an appropriate manner.
26
27 In addition to region-specific currency, date and time, Locale
28 adds more sophisticated formatting option than Layout provides:
29 numeric digit placement using '#' formatting, for example, is
30 supported by Locale - along with placement of '$', '-', and '.'
31 regional-specifics.
32
33 Locale is currently utf8 only. Support for both Utf16 and utf32
34 may be enabled at a later time
