  • reintegrates 'help' into 'trunk'
    • tweak arb documentation:
      • automatically link
        • ticket references to arb bug tracker (only affects html version).
        • found URLs.
      • page titles
        • warn about long titles.
        • introduce SUBTITLEs (automatically triggered by multi-line titles in source files).
        • increase allowed length (limited by subwindow width).
      • cleanup header sections in all helpfiles.
      • fix and/or update several help files.
      • document syntax of help sources.
      • build issues:
        • when xml validation fails, next build no longer uses invalid xml ⇒ keeps failing.
        • remove output files on error (including files below ARBHOME/lib).
        • pipe output through logs to ensure proper wrapping in Entering/Leaving lines.
    • moves Tree admin + NDS menu entries to top of menu
  • adds: log:branches/help@18783:19531

14OCCURRENCE      ARB_NT/Properties/Tree options/Expert settings
15
16DESCRIPTION     Provides the following expert display settings:
17
18                - 'Parent attach' defines the vertical position where the parent branch
19                  gets attached to a subtree (dendrogram view only).
20
21                  The first two criteria determine the position of normal branches using
22
23                  * the size of subtrees and
24                  * the length of child branches.
25
26                  The third criteria defines the position of branches towards
27                  folded groups.
28
29                  If a criterion is set to 1.0, the parent is attached
30                  nearer towards the bigger subtree or towards the longer child branch
31                  (or at the long side of the group polygone).
32
33                  If a criterion is set to -1.0 the parent is attached
34                  nearer towards the smaller subtree or towards the shorter child branch
35                  (or at the short side of the group polygone).
36
37                  The group attach position is an independent value.
38
39                  The other two criteria
40
41                   * depend on the proportion defined by child-branch-lengths
42                     and/or by subtree-sizes (ie. using the size-criterion
43                     will ALWAYS center the parent branch at two equal-sized
44                     subtrees - regardless what value is customized for the size criterion!)
45
46                   * influence each other. To understand the effect of each criterion it's recommended
47                     to set the other criterion to zero (in which case the criterion is ignored). If
48                     both criteria are non-zero the effect of each of them will be applied
49                     proportionally to their absolute values.
50
51                   * the traditional default setting (hardcoded up to arb 6.0.x) is -1.0 for
52                     size and 0.0 for length. In that case the parent branch is attached
53                     exactly between the lowest species of the upper subtree and the topmost
54                     species of the lower subtree.
55
56                  The traditional default setting (hardcoded up to arb 6.0.x) is -1.0 for
57                  size and 0.0 for length. In that case the parent branch is attached
58                  exactly between the lowest species of the upper subtree and the topmost
59                  species of the lower subtree.
60
61                - Text zoom/pad
62
63                  Select toggle to consider text for default zoom (otherwise only tree-structure is considered).
64                  Add extra padding in pixel (= amount of extra space for text; may be negative)
