+K2HDKC PHP Extension library
+
+@K2HDKCPX_EXT_PKGNAME@ implements a K2HDKC library as a PHP Extension
+written in C.
+
+K2HDKC is NoSQL(key value store) library and tools for this
+library by Yahoo! JAPAN.  
+This PHP Extension library is for using K2HDKC from PHP.
+
+By K2HDKC PHP Extension library, you can easily incorporate
+the functions and features of K2HCKD into PHP based programs.
+For the features of K2HDKC, see https://k2hdkc.antpick.ax/
