# 20180704 bkw: wrapper for snapscreenshot, determines the current tty
# and takes a screenshot of it by calling snapscreenshot with the
# appropriate arguments.
# I tried to make this work under X. You can find out which tty X is using
# with: xprop -root | grep ^XFree86_VT | cut -d' ' -f3
# However snapscreenshot itself fails because that console will be in
# graphics mode (no text to read from /dev/vcs$TTY, so it'd give a
# blank image).
