"Alternate Configuration Files\n"

|
|
"between different kernel configurations.\n"
|
|
"\n"
|
|
"At the end of the main menu you will find two options. One is\n"
|
|
"for saving the current configuration to a file of your choosing.\n"
|
|
"The other option is for loading a previously saved alternate\n"
|
|
"configuration.\n"
|
|
"\n"
|
|
"Even if you don't use alternate configuration files, but you\n"
|
|
"find during a Menuconfig session that you have completely messed\n"
|
|
"up your settings, you may use the \"Load Alternate...\" option to\n"
|
|
"restore your previously saved settings from \".config\" without\n"
|
|
"restarting Menuconfig.\n"
|
|
"\n"
|
|
"Other information\n"
|
|
"-----------------\n"
|
|
"If you use Menuconfig in an XTERM window make sure you have your\n"
|
|
"$TERM variable set to point to a xterm definition which supports color.\n"
|
|
"Otherwise, Menuconfig will look rather bad. Menuconfig will not\n"
|
|
"display correctly in a RXVT window because rxvt displays only one\n"
|
|
"intensity of color, bright.\n"
|
|
"\n"

"Menuconfig will display larger menus on screens or xterms which are\n"

"set to display more than the standard 25 row by 80 column geometry.\n"

|
"In order for this to work, the \"stty size\" command must be able to\n"

"display the screen's current row and column geometry. I STRONGLY\n"
|
|
"RECOMMEND that you make sure you do NOT have the shell variables\n"
|
|
"LINES and COLUMNS exported into your environment. Some distributions\n"

"export those variables via /etc/profile. Some ncurses programs can\n"
