30 | Revision 1.20.2.2 2000/06/30 00:46:17 nzdl
|

---|
32 |
|
---|
33 |
|
---|
34 | Revision 1.21 2000/06/30 00:40:39 sjboddie
|
---|
35 | Tidied up a bit. Fixed bug in formattools. Nested If/Or's should now
|
---|
36 | work within formatstrings.
|
---|
37 |
|
---|
38 | Revision 1.20.2.1 2000/04/09 23:16:48 sjboddie

41 | Revision 1.20 2000/04/07 04:40:44 sjboddie
|
---|
42 | Reverted back to old DocumentHeader, DocumentTitles, DocumentImages etc.
|
---|
43 | from DocumentColumns stuff. I'll move the DocumentColumns stuff to a
|
---|
44 | separate development branch (New_Config_Format-branch) for now. The plan
|
---|
45 | is to redesign the configuration file format a bit and limit the number of
|
---|
46 | distributions floating around that take different configuration formats).
|
---|
47 |
|
---|
48 | Revision 1.19 2000/04/03 07:28:24 sjboddie

51 |
|
---|
52 | Revision 1.18 2000/03/31 03:04:31 nzdl

---|
70 |
|
---|
71 | Revision 1.12 1999/10/10 08:14:07 sjboddie
|
---|
72 | - metadata now returns mp rather than array
|
---|
73 | - redesigned browsing support (although it's not finished so
|
---|
74 | won't currently work ;-)
|
---|
75 |

84 |
|
---|
85 | Revision 1.8 1999/08/20 00:56:38 sjboddie

|
---|

100 | with icon and link arguments set
|
---|
101 |
|
---|
102 | Revision 1.3 1999/07/09 02:44:35 sjboddie

|
---|
104 | level meta
|
---|
105 |
|
---|
106 | Revision 1.2 1999/07/08 20:48:33 rjmcnab

109 | Revision 1.1 1999/07/07 05:49:34 sjboddie
|
---|
110 | had another crack at the format string code - created a new formattools
|
---|
