+ unified interface is provided via c4.
+
+
+Dependencies
+------------
+
+ c4 currently requires the following libraries:
+
+ * libfcgi
+ <http://www.fastcgi.com/>
+
+ * librrd_th (thread-safe version of librrd)
+ <http://oss.oetiker.ch/rrdtool/>
+
+ * libyajl
+ <http://lloyd.github.com/yajl/>
+
+ The "configure" script is currently kept minimal. It may therefore be
+ necessary to set the CPP- and LD-flags manually. In case of libyajl, which is
+ not built with libtool, you may need to set the rpath, too.
+
+ When building from the Git repository, you'll need to have flex and bison (or
+ possibly lex and yacc) installed. These two programs are used to generate the
+ code for parsing the config file. If you are building from a tarball, the
+ generated .c and .h files are included and you don't need to have these
+ programs installed.
