+# Test installation of the build2 toolchain distribution. Essentially, this
+# is an automated build2-toolchain/INSTALL.
+#
+# Usage: install [options] <build2-toolchain-archive> <build2-repo>
+#
+# -i <dir>
+#    Target installation directory instead of default /tmp/build2-install.
+#
+# -l <dir>
+#    Prerequisite library (libodb, libodb-sqlite) installation directory
+#    instead of default /usr/local.
+#
+# -s
+#    Use sudo when installing.
+#
+# -t
+#    Install toolchain only.
+#
+# --cxx <path>
+#    C++ compiler to use, g++ by default.
+#
+# --cxxflags <flags>
+#    C++ compiler flags to use, -W -Wall -Wno-unknown-pragmas by default.
+#
+# --cppflags <flags>
+#    Extra C++ preprocessor flags to use.
+#
+# For example:
+#
+# install /tmp/build2-toolchain-0.1.0.tar.gz http://pkg.cppget.org/1/alpha
+#
