This is a very simple docset viewer. Docsets are sqlite3 files
containing a search index and a directory structure of HTML 
files. They are used for reading technical documentation offline.

You can read more about them here:  https://kapeli.com/docsets
	
One or more "docset directories" can exist in your ~/.docset 
directory. If you have the Zeal program installed, the command
below will allow you to use the same docset files:

  ln -s .local/share/Zeal/Zeal/docsets .docset

The parameters --port and --docsets are used to override
the defaults.
