.Sh DESCRIPTION
.Nm
is a lightweight window manager for X based on dwm's source code.
It manages windows in maximized, floating and tiled layouts.
Either layout can be applied dynamically, optimizing the environment for the
application in use and the task performed.
.Pp
In maximized layout only one window can be seen at the moment, but you
can switch between them with hotkeys.
In floating layout windows can be resized and moved freely.
Dialog windows are always managed floating, regardless of the layout applied.
.Pp
Windows are grouped by tags. Each window can be tagged with one or
multiple tags. Selecting certain tags displays all windows with these tags.
.Pp
.Nm
draws a small border around windows to indicate the focus state and an
optional titlebar.
.Pp
The options are as follows:
.Bl -tag -width "XXXXXXXXXXXX"
.It Fl v
Prints version information to standard output, then exits.
.It Fl f Ar conf
Specifies an alternative configuration file.
By default,
.Nm
loads the configuration file from
.Pa ~/.echinus/echinusrc,
if present, then looks for the system-wide configuration file
.Pa CONFDIR/echinusrc .
