elpa-spinner - 1.7.4-3 main

This library provides functions to add spinners to the Emacs
modeline. Spinners are used to indicate that an operation is in
progress.
.
A spinner is a column or columns of the modeline where the character
displayed in that column or columns changes rapidly, looping through
a sequence of characters or strings, until the operation is
complete. For example, one spinner type provided by this package
loops through these four characters: ◰, ◳, ◲ and ◱.
