# make          alone should build the entire application
# make install  should build and install the entire application
# make installweb installs to website for download
# make installrepo installs to yum repo
#
# make tgz      makes $(TGZ) of entire tree for standalone or rpm build
# make rpm      makes $(RPM) packages built by dieharder.spec
# make svn      does a svn commit and creates the timestamp $(SVNTIME)
# make sync     does a svn commit and syncs to list of svn-tree hosts
#
# make clean    cleans the source directories
