+logout-manager.conf 5 "April 2020" logout-manager "File Formats and Conventions"
+==================================================
+# NAME
+logout-manager.conf - the configuration file for logout-manager
+# FILE FORMAT
+The file has an ini-style syntax and consists of sections and parameters. A section begins with the name of the section in square brackets and continues until the next section begins. An example:
+
+    [section]
+    key = "value"
+    key2 = value2
+
+Put a value in double quotes if you need the white space preserved.  
+logout-manager.conf must be a regular file, and readable by all users who are permitted to run logout-manager. This is usually the same users who are permitted to log in to a graphical session.
+# SECTIONS AND EXAMPLES
+### The [logout-manager] section
+Define the command for a given action.
+
+`Section parameters`
+
+lock_command, logout_command, hibernate_command, shutdown_command, reboot_command
+    The value will be invoked upon selection of the named action. Place a command with its parameters in double quotes.
+    Defaults:
+
+    lock_command="/usr/libexec/logout-manager/lm-helper lock"
+    logout_command="/usr/libexec/logout-manager/lm-helper logout"
+    hibernate_command="sudo /usr/libexec/logout-manager/lm-helper hibernate"

+logout-manager 7 "April 2020" logout-manager "Common configuration options"
+==================================================
+# NAME
+logout-manager - common configuration options
+# SYNOPSIS
+This program manages a list of options for common logout commands, and can be used by a number of front-ends, including:
+
+`logout-manager-cli`(1)  
+`logout-manager-gtk`(1)  
+`logout-manager-ncurses`(1)  
+`logout-manager-tcl`(1)  
+`logout-manager-trayicon`(1)
+
+Of the listed front-ends, the trayicon and cli are not recommended for aliasing to the short name `logout-manager`.
+
+The library for logout-manager uses a number of environment variables; see below.
+# ENVIRONMENT VARIABLES
+If the defaults file (nominally `/etc/sysconfig/logout-manager`) does not define the following variables, you can define them in your own situation.
+
+`LOGOUT_MANAGER_LIBPATH`=/usr/share/logout-manager
+
+`LOGOUT_MANAGER_CONF`=/etc/logout-manager.conf
+
+Additional environment variables are used.
+`DRYRUN`=1  If DRYRUN is set to any non-null value, the actions will instead only display what would be executed and will not execute the commands.
+
+# ACTIONS
+An action is one of the following.
+
+**lock** hide and password-protect current screen
+
+**logout** close this graphical session
+
+**hibernate** save session memory to disk and power off. Note that not all hardware supports this.
+
+**shutdown** power off
+
+**reboot** restarts the system
