This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

# make sure the output directory exists | |
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}" | |
# Step 1. Build Device and Simulator versions | |

# git-mv-with-history -- move/rename file or folder, with history. | |
# | |
# Moving a file in git doesn't track history, so the purpose of this | |
# utility is best explained from the kernel wiki: | |
# | |
# Git has a rename command git mv, but that is just for convenience. | |
# The effect is indistinguishable from removing the file and adding another | |
# with different name and the same content. |
