Yes, it was originally SunTools and was renamed
SunView. But, XView was a
bit different although my memory of it all might be fading.
XView was a library that mapped SunView calls into X. But, I have a faint
memory that there was more to it than that. I think that there was a
conversion program that one had to run on the source code as part of the
conversion, and that that processor put flagging comments in for things
that couldn't automatically be converted.
My memory tends to be agree but as it last appeared in Solaris 9 and I
have no Solaris 9 machines left, I cannot verify.
