 Packages
 --------
 Regular releases are sporadic.  git master should be stable enough.  You can get
 a package with the latest development version from Archlinux's AUR.

-Extensions
-----------
-As the original StarDict is a bit of a clusterfuck with regard to collation of
-dictionary entries, I had to introduce an additional `collation` field into the

-automatically reorders the index according to that locale (e.g. "cs_CZ").
-This operation may take a little while, in the order of seconds.

-Configuration
--------------
-To get a nicer look in 256color terminals, create _~/.config/sdtui/sdtui.conf_
-with the following.  Note that it is intended for black-on-white terminals.

-....
-[Settings]
-center-search = true
-underline-last = false
-hl-common-prefix = true
-watch-selection = true

-header = reverse
-header-active = ul
-search = ul

-odd = 16 255

-The `watch-selection` option makes the application watch the X11 primary
-selection for changes and automatically search for selected text.  This feature
-requires XCB.  Wayland is currently unsupported, but would require a compositor
-supporting the wlr-data-control protocol.  Luckily, some compositors, such as
-Sway, synchronize selections with Xwayland.
-
-You can also set up some dictionaries to be loaded at startup automatically:
-
-....
-[Dictionaries]
-name1 = ~/path/to/dict.ifo
-name2 = ~/another/dict.ifo
-....
-
-The names define how they will appear in the tab bar.
