 * Screen-capture program for Linux text consoles

 * The "vcs" and "vcsa" drivers give read/write access to a vt's video memory,
 * somewhat like direct access to segment 0xb800 under DOS. The vcs version is
 * character-only, the vcsa version is character-attribute. There's one for
 * each vt, and they're numbered 7,0+ and 7,128+, respectively, with
 * /dev/vcs[a]0 corresponding to "/dev/tty".
