 # 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.
