5c36a0eb | 37 | /* 1999-02-01 Jean-Francois Bignolles: added option '-m' to display |
d162fcb5 | 38 | * monday as the first day of the week. |
b50945d4 | 39 | * 1999-02-22 Arkadiusz Miśkiewicz <misiek@pld.ORG.PL> |
7eda085c KZ |
40 | * - added Native Language Support |
41 | * | |
d162fcb5 | 42 | * 2000-09-01 Michael Charles Pruznick <dummy@netwiz.net> |
66ee8158 KZ |
43 | * Added "-3" option to print prev/next month with current. |
44 | * Added over-ridable default NUM_MONTHS and "-1" option to | |
45 | * get traditional output when -3 is the default. I hope that | |
46 | * enough people will like -3 as the default that one day the | |
47 | * product can be shipped that way. | |

49 | * 2001-05-07 Pablo Saratxaga <pablo@mandrakesoft.com> | |
50 | * Fixed the bugs with multi-byte charset (zg: cjk, utf-8) | |
51 | * displaying. made the 'month year' ("%s %d") header translatable | |
52 | * so it can be adapted to conventions used by different languages | |
53 | * added support to read "first_weekday" locale information | |
54 | * still to do: support for 'cal_direction' (will require a major | |
55 | * rewrite of the displaying) and proper handling of RTL scripts | |
