In the past Blender came Bundled with a selection of scripts.
A scripts window & a scripts help browser & a menu with script category’s.
In Blender 2.5 this has dramatically changed.
Blender still comes with a selection of extra or bundled scripts.
These are called add ons.
To find these scripts in a recent build of Blender on Graphicall.
Go to User Preferences > Add ons
You now get to enable or disable scripts in the add-ons menu.
You can filter (browse) the scripts by category & choose the one’s you like or need.
You can add scripts to the add ons folder with the install script button.
This is great because it gives the user Choice.
For example, in the 3D View category, there’s the Spacebar menu.
Yep! It’s Back!
If you choose to enable it.
The Add On scripts that come with Blender are kept up to date with current Blender api.
The selection of scripts in add-ons are maintained by myself, ideasman & when possible,
the script authors themselves.
We follow the Blender release cycle & take pride in providing a decent variety of scripts.
In the near future i will be providing script bundles that include all the scripts not in the default selection.
This is a very good system.
