Currently there are docsets available from Django, jQuery, Ruby 1 and 2 [1], Appcelerator Titanium, ExtJS 4.1, Python 2.7.3, Sencha Touch 2.1, Qt 5 [2].
You can also use Dash's docsets by putting `.docset` directories in `$HOME/.local/share/zeal/docsets/` (Linux) or `C:\Users\[your username]\AppData\Local\zeal\docsets\` (Windows).
1.`ZEAL` format, as generated by scripts in `gendocsets/{python273,qt5}` directories. It's essentially a single sqlite table with `type`, `name`, `path` and `parent` columns.
2.`DASH` format, which is also similar single table, without the `parent` column.
3. So-called `ZDASH`, which is a more complex Xcode docset format, implemented in Zeal to allow reusing Dash's docsets.
Author of Dash [has suggested](https://github.com/jkozera/zeal/issues/1#issuecomment-13357189) a "docset exchange programme", allowing Zeal to use one Dash docset in return for each new generated-for-Zeal docset, so it's recommended to use the `DASH` format.
Any feedback, feature requests, or pull requests are welcome. Before starting to implement anything larger, especially items from the TODO list above, it would be good to contact me at jerzy dot kozera at gmail, to avoid duplicating work.
