# FIXME: This was copied from the CommandGuide makefile. Figure out
# how to get this stuff on the website.

# This special case is for keeping the CommandGuide on the LLVM web site
# up to date automatically as the documents are checked in. It must build
# the POD files to HTML only and keep them in the src directories. It must also
# build in an unconfigured tree, hence the ifdef. To use this, run
# make -s BUILD_FOR_WEBSITE=1 inside the cvs commit script.
