-# #
-# Tuxmath Configuration File #
-# #
-# The behavior of Tuxmath can be controlled to a great #
-# extent by editing this file with any and saving it in #
-# the default options location ($HOME/.tuxmath/options). #
-# The file consists of 'NAME = VALUE' pairs, one pair per #
-# line. Each option is one of the following types: #
-# #
-# boolean: 1 (synonyms 'true', 'T', 'yes', 'Y', 'on') #
-# or #
-# 0 (synonyms 'false, 'F', 'no', 'N', 'off') #
-# integer (i.e. non-fractional numbers) #
-# float (i.e decimal fractions) #
-# #
-# Lines beginning with '#' or ';' are ignored as comments. #
-# The synonyms for boolean '0' and '1' are accepted as #
-# input, but always written as '0' or '1' when Tuxmath #
-# writes a config file to disk. #
-# The file is organized with the more important options #
-# first. #
-############################################################

-############################################################
-# #
-# Game Mode #
-# #
-# Parameter: play_through_list (Boolean) #
-# Default: 1 #
-# #
-# Tuxmath generates a list of math questions based on #
-# parameters set below. By default, (play_through_list = #
-# 1) the questions are asked in a random order. #
-# Correctly answered questions are removed from the list. #
-# If the player fails to correctly answer a question #
-# before it hits a city, the question will be reinserted #
-# into the list in a random location. #
-# The player wins if all questions are answered correctly #
-# before the cities are destroyed. #
-# #
-# Alternatively, Tuxmath can be played in 'Arcade Mode' #
-# by setting play_through_list = 0 (i.e. 'false'). If this #
-# is done, all questions will be randomly reinserted into #
-# the list whether or not they are answered correctly, and #
-# the game continues as long as there is a surviving city. #

-# #
-# If 'allow_speedup' is enabled, it is also possible to #
-# dynamically adjust the speed to the player's performance #
-# by setting 'use_feedback' to 1. This feature attempts #
-# to speed the game up if it is too easy for the player, #

-# Tuxmath Configuration File #
-# #
-# The behavior of Tuxmath can be controlled to a great #
-# extent by editing this file with any and saving it in #
-# the default options location ($HOME/.tuxmath/options). #
-# The file consists of 'NAME = VALUE' pairs, one pair per #
-# line. Each option is one of the following types: #
-# #
-# boolean: 1 (synonyms 'true', 'T', 'yes', 'Y', 'on') #
-# or #
-# 0 (synonyms 'false, 'F', 'no', 'N', 'off') #
-# integer (i.e. non-fractional numbers) #
-# float (i.e decimal fractions) #
-# #
-# Lines beginning with '#' or ';' are ignored as comments. #
-# The synonyms for boolean '0' and '1' are accepted as #
-# input, but always written as '0' or '1' when Tuxmath #
-# writes a config file to disk. #
-# The file is organized with the more important options #
-# first. #
-############################################################

-############################################################
-# #
-# Game Mode #
-# #
-# Parameter: play_through_list (Boolean) #
-# Default: 1 #
-# #
-# Tuxmath generates a list of math questions based on #
-# parameters set below. By default, (play_through_list = #
-# 1) the questions are asked in a random order. #
-# Correctly answered questions are removed from the list. #
-# If the player fails to correctly answer a question #
-# before it hits a city, the question will be reinserted #
-# into the list in a random location. #
-# The player wins if all questions are answered correctly #
-# before the cities are destroyed. #
-# #
-# Alternatively, Tuxmath can be played in 'Arcade Mode' #
-# by setting play_through_list = 0 (i.e. 'false'). If this #
-# is done, all questions will be randomly reinserted into #
-# the list whether or not they are answered correctly, and #
-# the game continues as long as there is a surviving city. #

-# #
-# By default, the comets become faster and more numerous #
-# with each succeeding. The increase can be prevented #
-# by setting 'allow_speedup' to 0. #
-# #
-# If 'allow_speedup' is enabled, it is also possible to #
-# dynamically adjust the speed to the player's performance #
-# by setting 'use_feedback' to 1. This feature attempts #
-# to speed the game up if it is too easy for the player, #
-# and to slow it down if the player is having trouble. #

-# 'per_user_config' determines whether Tuxmath will look #

-# .tuxmath file and use the the global settings in the #
-# installation-wide config file. #
-# #
-# 'homedir' allows you to specify the location to look for #

-# specify this unless all users share the same login #
-# account. See the README for details on configuration. #
-# To enable this feature, remove the '#' comment mark and #
-# set the path as desired. #
-# #
-# These settings cannot be changed by an ordinary user, as #
-# they are ignored unless the config file is Tuxmath's #
