Description Robert Yang 2013-04-19 11:32:32 UTC 
There are too many lines in pn-depends.dot, packages-depends.dot and task-depends.dot, which makes the output picture very big and hard to read, for example:

1) bitbake -g core-image-sato
2) dot -Tpng -o pn-depend.png pn-depends.dot

Then pn-depend.png would be around 5M, and the size is 32767 * 438 pixes, a very *long* picture.

Maybe we can remove the indirect depends to make it more readable, for example:

   A -> B
   B -> C
   A -> C 

The "A -> C" can be removed/hided

We may do it in either of the following way:

1) Enhance "bitbake -g" to remove/hide the indirect depends.

Or

2) Add a single script in oe-core/scripts to remove/hide the indirect depends for the dot file.

Command 'tred' from package ghaphviz is used to remove edges implied by transitivity in dot file.
