dmenut is an efficient dynamic menu for X.
This fork changes only a few key mappings and -hb flag for adding extra height of the bar.
In order to build dmenut you need the Xlib header files.
Edit config.mk to match your local setup (dmenut is installed into the /usr/local namespace by default).
Afterwards enter the following command to build and install dmenu (if necessary as root):
make clean install
See the man page for detail.
