[chuck-users] getting started questions

[Michael Heuer]

Hello Steve, welcome to ChucK!

LiCK is implemented with one public ChucK class (and zero or more
non-public classes) per .ck file and a bunch of Machine.add()
statements in one .ck file (import.ck).  It ain't pretty but it works.

One of my top outstanding ChucK language feature requests is to add
namespaces and import statements so that library/shared code can be
made modular.

I thought I saw somewhere hidden in new features (probably related to
Chugins) that there is a magick library directory where one can place
.ck files and have them loaded at startup.  Might this be a workaround
for having to use the import.ck file explicitly?
