+XMenu is a menu utility for X.
+XMenu receives a menu specification in stdin, shows a menu for the user
 to select one of the options, and outputs the option selected to stdout.
+XMenu can be controlled both via mouse and via keyboard.  The menu is a
+pop-up menu (that is, after selecting an option, the menu disappears).
+
+NOTE:
+The -w (windowed) option was removed from the master branch.  It was too
+buggy in tiled window managers and required more code to be maintained.
+
+
+§ Files
+
+The files are:
+• ./README:     This file.
+• ./Makefile:   The makefile.
+• ./config.h:   The hardcoded default configuration for XMenu.
+• ./config.mk:  The setup for the makefile.
+• ./xmenu.1:    The manual file (man page) for XMenu.
+• ./xmenu.c:    The source code of XMenu.
+• ./xmenu.sh:   A sample script illustrating how to use XMenu.

+creates the binary file ./xmenu.
 
-Edit config.mk to match your local setup (xmenu is installed into the
-/usr/local prefix by default).  Then enter the following command to
-build and install xmenu (if necessary as root).

-	make clean install
+By default, XMenu is installed into the /usr/local prefix.  Enter the

+§ Running XMenu
+
+XMenu receives as input a menu specification where each line is a menu
 entry.  Each line can be indented with tabs to represent nested menus.
 Each line is made out of a label and a command separated by any number
 of tabs.  Lines without labels are menu separators.
 
-See the script ./xmenu.sh for an example of how xmenu can be used to
-draw a simple menu with submenus and separators.
