   4 Subject: [PATCH] More specific library linking
   5
   6 Currently, the main binary and all output modules are linked to the same
   7 set of libraries. This changes the linking so that only the main binary
   8 is linked to pcap, and only addrwatch_mysql is linked to mysqlclient.
   9
  10 This allows the main binary and output modules to be packaged separately
  11 with fewer dependencies for each individual package.
