92 | "\n" | |

96 | "configuration.\n" | |

98 | "Even if you don't use alternate configuration files, but you\n" | |
99 | "find during a nconfig session that you have completely messed\n" | |

101 | "restore your previously saved settings from \".config\" without\n" | |
102 | "restarting nconfig.\n" | |
103 | "\n" | |
104 | "Other information\n" | |
105 | "-----------------\n" | |
106 | "If you use nconfig in an XTERM window make sure you have your\n" | |
107 | "$TERM variable set to point to a xterm definition which supports color.\n" | |
108 | "Otherwise, nconfig will look rather bad. nconfig will not\n" | |

117 | "LINES and COLUMNS exported into your environment. Some distributions\n" | |
118 | "export those variables via /etc/profile. Some ncurses programs can\n" | |
