1.19 +"Overview\n"
1.20 +"--------\n"
1.21 +"This interface let you select features and parameters for the build.\n"
1.22 +"Features can either be built-in, modularized, or ignored. Parameters\n"
1.23 +"must be entered in as decimal or hexadecimal numbers or text.\n"
1.24 +"\n"
1.25 +"Menu items beginning with following braces represent features that\n"
1.26 +" [ ] can be built in or removed\n"
1.27 +" < > can be built in, modularized or removed\n"
1.28 +" { } can be built in or modularized (selected by other feature)\n"
1.29 +" - - are selected by other feature,\n"
1.30 +" XXX cannot be selected. Use Symbol Info to find out why,\n"
1.31 +"while *, M or whitespace inside braces means to build in, build as\n"
1.32 +"a module or to exclude the feature respectively.\n"
1.33 +"\n"
1.34 +"To change any of these features, highlight it with the cursor\n"
1.35 +"keys and press <Y> to build it in, <M> to make it a module or\n"
1.36 +"<N> to removed it. You may also press the <Space Bar> to cycle\n"
1.37 +"through the available options (ie. Y->N->M->Y).\n"
1.38 +"\n"
1.39 +"Some additional keyboard hints:\n"
1.40 +"\n"
1.41 +"Menus\n"
1.42 +"----------\n"
1.43 +"o Use the Up/Down arrow keys (cursor keys) to highlight the item\n"
1.44 +" you wish to change use <Enter> or <Space>. Goto submenu by \n"
1.45 +" pressing <Enter> of <right-arrow>. Use <Esc> or <left-arrow> to go back.\n"
1.46 +" Submenus are designated by \"--->\".\n"
1.47 +"\n"
1.48 +" Searching: pressing '/' triggers interactive search mode.\n"
1.49 +" nconfig performs a case insensitive search for the string\n"
1.50 +" in the menu prompts (no regex support).\n"
1.51 +" Pressing the up/down keys highlights the previous/next\n"
1.52 +" matching item. Backspace removes one character from the\n"
1.53 +" match string. Pressing either '/' again or ESC exits\n"
1.54 +" search mode. All other keys behave normally.\n"
1.55 +"\n"
1.56 +" You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n"
1.57 +" unseen options into view.\n"
1.58 +"\n"
1.59 +"o To exit a menu use the just press <ESC> <F5> <F8> or <left-arrow>.\n"
1.60 +"\n"
1.61 +"o To get help with an item, press <F1>\n"
1.62 +" Shortcut: Press <h> or <?>.\n"
1.63 +"\n"
1.64 +"\n"
1.65 +"Radiolists (Choice lists)\n"
1.66 +"-----------\n"
1.67 +"o Use the cursor keys to select the option you wish to set and press\n"
1.68 +" <S> or the <SPACE BAR>.\n"
1.69 +"\n"
1.70 +" Shortcut: Press the first letter of the option you wish to set then\n"
1.71 +" press <S> or <SPACE BAR>.\n"
1.72 +"\n"
1.73 +"o To see available help for the item, press <F1>\n"
1.74 +" Shortcut: Press <H> or <?>.\n"

1.76 +"\n"
1.77 +"Data Entry\n"
1.78 +"-----------\n"
1.79 +"o Enter the requested information and press <ENTER>\n"
1.80 +" If you are entering hexadecimal values, it is not necessary to\n"
1.81 +" add the '0x' prefix to the entry.\n"
1.82 +"\n"

1.84 +"\n"
1.85 +"\n"
1.86 +"Text Box (Help Window)\n"
1.87 +"--------\n"
1.88 +"o Use the cursor keys to scroll up/down/left/right. The VI editor\n"

1.90 +" who are familiar with less and lynx.\n"

1.93 +"\n"
1.94 +"\n"
1.95 +"Alternate Configuration Files\n"
1.96 +"-----------------------------\n"
1.97 +"nconfig supports the use of alternate configuration files for\n"
1.98 +"those who, for various reasons, find it necessary to switch\n"
1.99 +"between different configurations.\n"
1.100 +"\n"
1.101 +"At the end of the main menu you will find two options. One is\n"
1.102 +"for saving the current configuration to a file of your choosing.\n"
1.103 +"The other option is for loading a previously saved alternate\n"
1.104 +"configuration.\n"
1.105 +"\n"
1.106 +"Even if you don't use alternate configuration files, but you\n"
1.107 +"find during a nconfig session that you have completely messed\n"
1.108 +"up your settings, you may use the \"Load Alternate...\" option to\n"
1.109 +"restore your previously saved settings from \".config\" without\n"
1.110 +"restarting nconfig.\n"
1.111 +"\n"
1.112 +"Other information\n"
1.113 +"-----------------\n"
1.114 +"If you use nconfig in an XTERM window make sure you have your\n"
1.115 +"$TERM variable set to point to a xterm definition which supports color.\n"
1.116 +"Otherwise, nconfig will look rather bad. nconfig will not\n"
1.117 +"display correctly in a RXVT window because rxvt displays only one\n"
1.118 +"intensity of color, bright.\n"
1.119 +"\n"
1.120 +"nconfig will display larger menus on screens or xterms which are\n"
1.121 +"set to display more than the standard 25 row by 80 column geometry.\n"
1.122 +"In order for this to work, the \"stty size\" command must be able to\n"
1.123 +"display the screen's current row and column geometry. I STRONGLY\n"
1.124 +"RECOMMEND that you make sure you do NOT have the shell variables\n"
1.125 +"LINES and COLUMNS exported into your environment. Some distributions\n"
1.126 +"export those variables via /etc/profile. Some ncurses programs can\n"
1.127 +"become confused when those variables (LINES & COLUMNS) don't reflect\n"
1.128 +"the true screen size.\n"
1.129 +"\n"
1.130 +"Optional personality available\n"
1.131 +"------------------------------\n"
1.132 +"If you prefer to have all of the options listed in a single menu, rather\n"
1.133 +"than the default multimenu hierarchy, run the nconfig with NCONFIG_MODE\n"
1.134 +"environment variable set to single_menu. Example:\n"
1.135 +"\n"
1.136 +"make NCONFIG_MODE=single_menu nconfig\n"
