In order to build dmenu you need the Xlib header files.
You also need libdraw, available from http://hg.suckless.org/libdraw
Pasting the X selection to dmenu requires the sselp utility at runtime.
Installation
------------
Edit config.mk to match your local setup (dmenu is installed into
the /usr/local namespace by default).

.B dmenu
is a generic menu for X, originally designed for
.BR dwm (1).
It manages huge amounts (up to 10.000 and more) of user defined menu items
efficiently.
dmenu_run is a dmenu script used by dwm which lists executables in the user's PATH
and executes the selected item.
dmenu_path is a script used by dmenu_run to find and cache a list of executables.
It manages huge amounts (10000 and more) of user defined menu items efficiently.
.P
.B dmenu_run
is a dmenu script which lists programs in the user's PATH and executes
the selected item.
.P
.B dmenu_path
is a script used by
.I dmenu_run
to find and cache a list of programs.
.SS Options
.TP
.B \-i
makes dmenu match menu entries case insensitively.
.TP
.B \-b
defines that dmenu appears at the bottom.
dmenu appears at the bottom of the screen.
.TP
.B \-e <xid>
reparents dmenu to the window specified by xid.
.B \-i
dmenu matches menu entries case insensitively.
.TP
.B \-l <lines>
activates vertical list mode.
The given number of lines will be displayed. Window height will be adjusted.
.TP

.SH USAGE
dmenu reads a list of newline-separated items from standard input and creates a
menu. When the user selects an item or enters any text and presses Return, his/her
choice is printed to standard output and dmenu terminates.

dmenu is completely controlled by the keyboard. Besides standard Unix line editing,
and item selection (Up/Down or Left/Right, PageUp/PageDown, Home/End), the following
keys are recognized:
