# All extensions

For easier tracking, this is a list of all current extensions by number which can easily be regenerated from vk.xml.
Every item in this list should be in one of the lists above, so if it's not then it's a new extension and should be filed.

Generate with:
```
grep '<extension ' vk.xml |
   sed -e '{s#.*name="\([^"]*\)".*number="\([0-9]*\)".*#\2    \1#g}' |
   sed -e '{s#\<[0-9]\>#00&#g}' | sed -e '{s#\<[0-9][0-9]\>#0&#g}' |
   grep -Ev 'extension_[0-9]*$' | grep -v RESERVED
```
