+Unless you specifically only need the build2 build system, you should install
+the entire build2 toolchain instead, either using the install script
+(https://build2.org/install.xhtml) or the build2-toolchain distribution.
+
+The instructions outlined below are essentially a summary of the first three
+steps of the manual bootstrap process described in build2-toolchain with a few
+extra examples that would primarily be useful for distribution packaging.
+
+Also, below we only show commands for UNIX-like operating systems. For other
+operating systems and for more details on each step, refer to the
+build2-toolchain installation documentation.
+
+build2 requires a C++14 compiler. GCC 4.9, Clang 3.7, and MSVC 14 (2015) Update
+3 or any later versions of these compilers are known to work. The build system
+is self-hosted, which means that unless you have obtained a pre-built binary
+from somewhere else, you will need to bootstrap it. To accomplish this, we use
+the bootstrap.sh shell script (or equivalent batch files for Windows) found in
+the root directory of the build2 distribution. On UNIX-like operating systems
+as well as on Windows with MinGW or Clang, a GNU make makefile called
+bootstrap.gmake can also be used with the major advanage over the script being
+support for parallel compilation and an out of tree build (see comments inside
+the makefile for more information).
+
+The following is the recommended sequence of steps:
+
+0. Prerequisites
+
+ Get libbutl (normally from the same place where you got build2) and place
+ it inside build2, so that you have:
+
+ build2-X.Y.Z
+ |
+ `-- libbutl-X.Y.Z
+
+1. Bootstrap, Phase 1
+
+ First, we build a minimal build system using bootstrap.sh (run bootstrap.sh
+ -h for options):
+
+ $ cd build2-X.Y.Z
+ $ ./bootstrap.sh g++
+
+ $ build2/b-boot --version
+
+ Alternatively, we can use the bootstrap.gmake makefile:
+
+ $ cd build2-X.Y.Z
+ $ make -f bootstrap.gmake -j 8 CXX=g++
+
+ $ build2/b-boot --version
+
+ If you would prefer to bootstrap out of source tree, this is supported by
+ the makefile (but not the script):
+
+ $ mkdir build2-boot
+ $ make -C build2-boot -f ../build2-X.Y.Z/bootstrap.gmake -j 8 CXX=g++
+
+ $ build2-boot/build2/b-boot --version
+
+2. Bootstrap, Phase 2
+
+ Then, we rebuild the build system with the result of Phase 1 linking
+ libraries statically.
+
+ $ build2/b-boot config.cxx=g++ config.bin.lib=static build2/exe{b}
+ $ mv build2/b build2/b-boot
+
+ $ build2/b-boot --version
+
+ Or, alternatively, for an out of tree build:
+
+ $ build2-boot/build2/b-boot config.cxx=g++ config.bin.lib=static \
+ build2-X.Y.Z/build2/@build2-static/build2/exe{b}
+
+ $ build2-static/build2/b --version
+
+3. Build and Install
+
+ Finally, we configure, build, and optionally install the "final" version
+ using shared libraries:
+
+ $ build2/b-boot configure \
+ config.config.hermetic=true \
+ config.cxx=g++ \
+ config.cc.coptions=-O3 \
+ config.bin.rpath=/usr/local/lib \
+ config.install.root=/usr/local \
+ config.install.sudo=sudo
+
+ $ build2/b-boot
+
+ | The config.config.hermetic=true configuration variable in the first
+ | command makes sure the embedded ~host and ~build2 configurations include
+ | the current environment. This is especially important for ~build2 which
+ | is used to dynamically build and load ad hoc recipes and build system
+ | modules and must therefore match the environment that was used to build
+ | the build system itself.
+
+ If you are only interested in installing the result, then you can avoid
+ building tests by specifying the update-for-install operation in the last
+ command:
+
+ $ build2/b-boot update-for-install
+
+ On the other hand, if I you are not planning to install the result, then
+ you can omit the config.install.* values as well as .rpath.
+
+ To install:
+
+ $ build2/b-boot install
+ $ which b
+ $ b --version
+
+ To uninstall:
+
+ $ b uninstall
+ $ which b
+
+ Or, alternatively, for an out of tree build:
+
+ $ build2-static/build2/b configure: build2-X.Y.Z/@build2-shared/ \
+ config.config.hermetic=true \
+ config.cxx=g++ \
+ config.cc.coptions=-O3 \
+ config.bin.rpath=/usr/local/lib \
+ config.install.root=/usr/local \
+ config.install.sudo=sudo
+
+ $ build2-static/build2/b update-for-install: build2-shared/
+
+ $ build2-static/build2/b install: build2-shared/
+
+ $ b uninstall: build2-shared/
+
+ For distribution packaging it is often required to install "as if" into the
+ system directory (for example, /usr) but to copy the files somewhere else
+ (for example, /tmp/install/usr; aka the DESTDIR functionality). In build2
+ this can be achieved with the config.install.chroot configuration variable,
+ for example:
+
+ $ build2-static/build2/b configure: build2-X.Y.Z/@build2-shared/ \
+ config.config.hermetic=true \
+ config.cxx=g++ \
+ config.cc.coptions=-O3 \
+ config.install.root=/usr \
+ config.install.chroot=/tmp/install
