+The aim of this package is to make reading the INSTALL file unnecessary. So
+next time try running:
+
+$ bpkg build libicuio
+
+But if you don't want to use the package manager, then you can also build this
+package manually using the standard build2 build system.

+International Components for Unicode (ICU) is a set of cross-platform Unicode-
+based globalization libraries with libicuio C/C++ library providing
+input/output support (writing Unicode string to std::ostream, etc). For more
+information see:
+
+http://site.icu-project.org/
+
+This package contains the original libicuio library source code overlaid with
+the build2-based build system and packaged for the build2 package manager
+(bpkg).
+
+See the INSTALL file for the prerequisites and installation instructions.
+
+Send questions, bug reports, or any other feedback about library itself to the
+ICU mailing lists. Send build system and packaging-related feedback to the
+packaging@build2.org mailing list (see https://lists.build2.org for posting
+guidelines, etc).
+
+The packaging of libicuio for build2 is tracked in a Git repository at:
+
+https://git.build2.org/cgit/packaging/icu/

+This document describes how libicuio was packaged for build2. In particular,
