docs-rst: create an user's manual book
Place README, REPORTING-BUGS, SecurityBugs and kernel-parameters
on an user's manual book.
As we'll be numbering the user's manual, remove the manual
numbering from SecurityBugs.

Normally, you -can set the size of hardware cursor (and also work around some ugly bugs in -those miserable Trident cards [#f1]_. You can now play a few new tricks: -you can make your cursor look - -like a non-blinking red block, make it inverse background of the character it's -over or to highlight that character and still choose whether the original -hardware cursor should remain visible or not. There may be other things I have -never thought of. - -The cursor appearance is controlled by a ``<ESC>[?1;2;3c`` escape sequence -where 1, 2 and 3 are parameters described below. If you omit any of them, -they will default to zeroes. - -first Parameter - specifies cursor size:: - - 0=default - 1=invisible - 2=underline, - ... - 8=full block - + 16 if you want the software cursor to be applied - + 32 if you want to always change the background color - + 64 if you dislike having the background the same as the - foreground. - - Highlights are ignored for the last two flags. - -second parameter - selects character attribute bits you want to change - (by simply XORing them with the value of this parameter). On standard - VGA, the high four bits specify background and the low four the - foreground. In both groups, low three bits set color (as in normal - color codes used by the console) and the most significant one turns - on highlight (or sometimes blinking -- it depends on the configuration - of your VGA). - -third parameter - consists of character attribute bits you want to set. - - Bit setting takes place before bit toggling, so you can simply clear a - bit by including it in both the set mask and the toggle mask. - -.. [#f1] see ``#define TRIDENT_GLITCH`` in ``drivers/video/vgacon.c``. - -Examples: -========= - -To get normal blinking underline, use:: - - echo -e '\033[?2c' - -To get blinking block, use:: - - echo -e '\033[?6c' - -To get red non-blinking block, use:: - - echo -e '\033[?17;0;64c' |
