echinus is a dynamic window manager for X11 supporting managing windows in floating, tiled and maximized layouts based on dwm. All the configuration is made via a config file in Xresources format, so it is not necessary to recompile echinus every time you change something. echinus supports a small subset of EWMH to be compatible with external panels and pagers. It draws a border around windows and also an optional title bar. The goal of development is a small, fast window manager without features not strictly related to window management (menus, panels, etc.).
