While it is true that I pre-date C++, I had no involvement with that programming language or library. Sorry!
When I began computing, computing was just beginning. E.g. Analog computing was the way things were done, and there were no "computer chips." Later came foot-square "memory cards" that were hand-made grids of tiny magnetic doughnut-shaped "cores." (FYI: This is where the term "core memory" came from....)
It was a big day when chips came along, and program languages came to be! (For a while things moved even faster back then, I think....)
Programming as we know it now - high level, multipurpose programmed commands - would put the first "serious" / widespread programming language - the "C" programming language by Dennis Ritchie and Brian Kernighan (AKA "K&R") to shame, complexity-wise.
Some things stuck around, though: when I was doing computer graphics programming in the 70s I was using three different programming "languages:"
WATFIV, FORTRAN, and machine code
*.
Programming languages exploded in the 80s and thereafter, and made the old stuff like
FORTRAN-IV a joke.
The field exploded, of course, and derivatives of all sorts - with specialized needs - sprang up all over the place, too.
So it should be no surprise this library was created, and fittingly arbitrarily named, as well, I suppose!
Thanks for the note, BTW! I had no idea that I had a connection like that Fermilab connection!
(Aside from my LLNL connection.... )* Commands within the computer itself that afforded low-level "tweaking" of things, such as changing a bit in an in-memory command....
