(description
|

"Extempore is a programming language and runtime environment designed
|
||||
with live programming in mind. It supports interactive programming in a REPL
|
||||
style, compiling and binding code just-in-time. Although Extempore has its
|
||||
roots in 'live coding' of audiovisual media art, it is suitable for any task
|
||||
domain where dynamic run-time modifiability and good numerical performance are
|
||||
required. Extempore also has strong timing and concurrency semantics, which
|
||||
are helpful when working in problem spaces where timing is important (such as
|
||||
audio and video).")
