# scast - functions to create screencasts.
# This file:

#           (find-angg "bin/scast")
#      See: (find-angg "bin/git-defs")
#
# Usage: we can just source these functions into a shell, with
#
#   . ~/bin/scast
#
# but more typically we call this with a single argument, which is
# interpreted by the "eval" at the end. A call like
#
#   ~/bin/scast 'R=6;r;c;g'
#
# sets the frame rate to 6 FPS, moves to the desktop to the right,
# cleans the files in /tmp/ that can be leftovers of a previous
# screencast recording, and runs "avconv -f x11grab" with the right
# arguments; a call like
#
#   ~/bin/scast 'k'
#
# kills avconv and stops the recording.
#

# Used by: 
# (find-es "git" "git-test-2")
