is a generic, highly customizable, and efficient menu for the X Window System,
originally designed for
.BR wmii (1).
It supports arbitrary, user defined menu contents, which get executed.
Like wmii,
.B wmiimenu
also implements a socket-based fileserver, which is accessed to configure and
interoperate with other components.
It supports arbitrary, user defined menu contents, which get printed to stdout when selected.
.SS Options
.TP
.BI \-s " socketfile"
specifies the socketfile that
.B wmiimenu
should create.
.TP
.B \-v
prints version information to stderr, then exits.
.SS Customization
.B wmiimenu
is customized through manipulating its filesystem namespace.
In the default setup of
.BR wmii (1)
the namespace of
.B wmiimenu
can be found in /menu.
is customized by feeding it a list of newline-separated items from stdin.
