# This makefile is responsible for installing the documentation. The
# files to be installed are prepared specially and are placed in this
# directory during distribution bundling. In CVS-based trees these
# files don't exist, so we skip the installation in that case.
#
# Before we install the man pages, we massage the section numbers to
# follow the local conventions.
#
# To actually build the documenation, look into the src/ and src/sgml
# subdirectories.
