.SH DESCRIPTION
.B dmenu
is a dynamic menu for X, originally designed for
.IR dwm (1).
It manages huge numbers of user\-defined menu items efficiently.

dmenu reads a list of newline\-separated items from stdin and creates a menu.
When the user selects an item or enters any text and presses Return, their
choice is printed to stdout and dmenu terminates.

dmenu grabs the keyboard before reading stdin. This is faster, but will lock up
