Subject: Fixed a few hard-coded database names in the makefile.
X-Git-Url: https://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=f3b83c7b5212079afae3621b85ad9beb047b1ace;p=dead%2Fcensus-tools.git

Fixed a few hard-coded database names in the makefile.
Updated the makefile with some new targets to separate the block data from that of the lines.
Include the SF1/TIGER blocks combination in the blocks_db and db targets.
