# bin2cc - embedding compressed data in C files.

# 

# 1) Do what the fuck you want with this code.

# 

##################

# Examlpe:

# Create the C file with the compressed data:

# $ python3 bin2cc.py ../xorg.png > test.c

# 

# Add this to the end of the file:

# 

#int main (int argc, char ** argv) {

#  

#  unsigned char * out_buff = malloc(_xorg_png_real_len);

#  

#  uLongf outlen;

#  

#  uncompress (out_buff, &outlen, _xorg_png, _xorg_png_len);

#  

#  FILE * f = fopen ("../xorg_2.png", "wb");

#  fwrite (out_buff, 1, _xorg_png_real_len, f);

#  fclose (f);

#  return 0;

#}
