This collection is pruned and more suited specifically for animators, riggers and Python devs. These are tools I find useful in my work. master branch is more general and periodically synced with meta-androcto's repo.

• Blender 2.76+ build from buildbot.
• blenderpython zip, unpacked.
• Included in this repo: addon_utils.py, space_view3d.py
• Optional: Use Blender's config folders to keep a special config for addons_extern.

• Using addons_extern, there is no need to mix external addons with Blender's bundled addons. Upgrading requires less filtering and easier maintenance.
• addons_extern often serves as a home for abandoned addons, with fixes for later versions of blender.
• addons_extern should be placed next to addons & addons contrib in $BLENDER_ROOT\2.76\scripts

• Use at your own risk!
• Some addons are hard coded to addons_extern folder.
• Open the _init_.py file for the addon & shortly below the addon information there will be text with path & addons in it.
• Be careful using addons_extern! Some addons work on large amounts of data, resulting in slow calculations and higher potential to crash.
• Save Often. I'm not responsible for any lost effort or broken addons.
