DESCRIPTION
agg (asciinema gif generator) converts asciinema terminal recordings to animated GIF files.

INSTALL
CAVEATS
Large or long recordings produce large GIF files. Consider adjusting speed or idle-time-limit to reduce file size. Font rendering quality depends on available system fonts.
HISTORY
agg was created as a Rust-based alternative to other asciinema-to-GIF tools, providing better performance and rendering quality. It's maintained as part of the asciinema ecosystem.
