There have been a number of ideas floated, such as a dependency tree based
on libraries, that I wanted to tackle in C++ rather than one of the
traditional scripting languages. Hence the detour to do the filesystem

Having a relatively easy way to identify libraries will further ease the

Perhaps it might be possible to use the dependency information to drive a
download process that only pulled in what was asked for, plus
dependencies. I think cygwin does that now in their setup wizard.
