# Documentation Overview
#
# There are two main source materials for libstdc++ documentation.
# The first is the doxygen markup in libstdc++ sources, which is a
# reference to the API. And the second is the docbook markup in
# doc/xml/.
#
# A third and more obscure option deals with charting
# performance tests, and should be considered experimental.

# Default rules.
#
# Point to best sub-rule for the requested documentation target,
# create, and then copy into toplevel directory with standardized names
# and layouts.
