#
# Note that when refering to libraries that use auto-index we must process all the way to
# docbook before including here.  We must also ensure that auto-index uses it's own index
# generation, otherwise we get one big index that's repeated in each library.  Xslt's index
# generation is also so slow that it's impractical for a build this large (takes ~ 9 hrs
# to build with just 3 indexed libraries).  Hence we refer to these libraries as for example:
#
# ../libs/interprocess/doc//standalone/<format>docbook
#
# Within each library that uses this, make sure that the boostbook target contains
#
# <format>docbook:<auto-index-internal>on
#
# And if boost.root is set, restrict it to local html builds using:
#
# <format>html:<xsl:param>boost.root=../../../..
# <format>html:<xsl:param>boost.libraries=../../../../libs/libraries.htm
#
# Finally, in boost.xml we xi:include interproces.auto_index.docbook which is the final
# post-index generation docbook, rather than interprocess.xml which is the pre-indexed boostbook.
