+bspwm is a tiling window manager that represents windows as the
+leaves of a full binary tree. It is controlled and configured
+via bspc.
+
+before launching it, you need some configuration files: you can
+can find some example ones in /usr/doc/bspwm-$VERSION/examples:
+- bspwmrc, should go to ~/.config/bspwm/bspwmrc
+- sxhkdrc, should go to ~/.config/sxhkd/sxhkdrc
+
+dmenu is an optional dependency.

++
++floating::
++    Is above any tiled window and can be moved/resized freely. Although it doesn't occupy any tiling space, it is still part of the window tree.
++
++fullscreen::
++    Fills its monitor rectangle, is above all the other windows and has no borders.
++
++locked::
++    Ignores the *close* message.
++
++sticky::
++    Stays in the focused desktop of its monitor.
++
++private::
++    Tries to keep the same tiling position/size.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
