-Aegisub is an advanced subtitle editor for Windows, and UNIX-like systems, such
-as Linux, Mac OS X and BSD. It is open source software and free for any use.

-Aegisub natively works with the Advanced SubStation Alpha format (aptly
-abbreviated ASS) which allows for many advanced effects in the subtitles, apart
-from just basic timed text. Aegisub's goal is to support using these advanced
-functions with ease.
