NAME
get_y_rotate_matrix, get_y_rotate_matrix_f - Construct Y axis rotation matrices. Allegro game programming library.

SYNOPSIS
#include <allegro.h>

void get_y_rotate_matrix(MATRIX *m, fixed r);

void get_y_rotate_matrix_f(MATRIX_f *m, float r);

DESCRIPTION
Construct Y axis rotation matrices, storing them in m. When applied to a point, these matrices will rotate it about the Y axis by the spec-
ified angle (given in binary, 256 degrees to a circle format).

NAME
get_rotation_matrix, get_rotation_matrix_f - Constructs X, Y, Z rotation matrices. Allegro game programming library.

SYNOPSIS
#include <allegro.h>

void get_rotation_matrix(MATRIX *m, fixed x, fixed y, fixed z);

void get_rotation_matrix_f(MATRIX_f *m, float x, float y, float z);

DESCRIPTION
Constructs a transformation matrix which will rotate points around all three axes by the specified amounts (given in binary, 256 degrees to
a circle format). The direction of rotation can simply be found out with the right-hand rule: Point the dumb of your right hand towards the
origin  along  the axis of rotation, and the fingers will curl in the positive direction of rotation. E.g. if you rotate around the y axis,
and look at the scene from above, a positive angle will rotate in clockwise direction.

## Shopt -s histappend

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file. # When the shell exits, append to the history file instead of overwriting it shopt -s histappend

## Undeletable file

Greetings, I'm trying to delete a file with a weird name from within Terminal on a Mac. It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘. Here are some examples of what I've tried: 12FX009:5 dpontius\$ ls ââWord FinderÂŽ Plusâ˘ 12FX009:5 dpontius\$ rm...
