[$] Asciinema: making movies at the command-line

In open-source circles there are many situations, such as bug
reports, demos, and tutorials, when one might want to provide a
play-by-play of a session in one’s terminal. The asciinema project provides a set of
tools to do just that. Its tools let users record, edit, and share
terminal sessions in a text-based format that has quite a few
advantages compared to making and sharing videos of terminal sessions. For
example, it is easy to use, offers the ability to search text from
recorded sessions, and allows users to copy and paste directly from
the recording.
