I mean LGPL is Library GPL a bit differently type of license from just GPL .
"The GNU Project has two principal licenses to use for libraries. One is
the GNU Lesser GPL; the other is the ordinary GNU GPL. The choice of
license makes a big difference: using the Lesser GPL permits use of the
library in proprietary programs; using the ordinary GPL for a library makes
it available only for free programs."
I think Adam hopes for wider use of guicast as GUI library, so files there
(as of now) LGPL. Usually exact license text derived from moment code was
So look into cin hv 4.x tree, I guess?

well, merges from CV into GG (But not HV) documented in git history .... so
I see no reason to complain - cingg says its own startup message, cin HV
uses their own code and show their own message....

see my next email about fileffmpeg.C investigation.
Archive is not supported, but you still can download ~600 mb of git history
from there unavailable anywhere else (in this sense google code archive is
neutral third party)
I do not want to confuse CinGG with all of the rest of the other Cinelerra

Well, I think in general template message is correct, just we need pay
attention when more than one author worked on it. You can look into
ffmpeg's sources for some examples. Dates for (c) usually not exact, but at
least year or range of years provided.
Or correct the one below that I have added both Adam and CV to for when I
