to find the result the user intended.  It does this by favouring matches on
consecutive letters and starts of words.  This allows matching using acronyms
or different parts of the path.

fzy is designed to be used both as an editor plugin and on the command
line.  Rather than clearing the screen, fzy displays its interface directly
below the current cursor position, scrolling the screen if necessary.")
