# Doxygen HTML help is not suitable for packaging due to a minified JavaScript
# bundle inserted by Doxygen itself. See discussion at
# https://bugzilla.redhat.com/show_bug.cgi?id=2006555.
#
# We can enable the Doxygen PDF documentation as a substitute.
#
# We still generate the HTML documentation, but strip out all the JavaScript
# that causes policy issues. This degrades it in the browser, but is sufficient
# to keep the Devhelp documentation working.

# Based on discussion in
# https://src.fedoraproject.org/rpms/pangomm/pull-request/2, cairomm will
# continue to provide API/ABI version 1.0 indefinitely, with the cairomm1.16
# package providing the new 1.16 API/ABI series. This virtual Provides is
# therefore no longer required, as dependent packages requiring the 1.0 API/ABI
# may safely require cairomm and its subpackages.

%description
This library provides a C++ interface to cairo.

The API/ABI version series is %{apiver}.

# We must remove the jQuery/jQueryUI bundle with precompiled/minified/bundled

# XML too. Note that we will still install the HTML documentation, since the
# devhelp XML requires it, but we will strip out the JavaScript, which will
