build2 utility library

This package contains the build2 utility library.

build2 is an open source, cross-platform toolchain for building and packaging
C++ code. Its aim is a modern build system and dependency manager for the C++
language that provide a consistent, out of the box interface across multiple
platforms and compilers. For more information see:

https://build2.org/

This library is a collection of utilities that are used throughout the
toolchain.
