-Libmemcached is layed out by interface version. The 1.0 version would be found in:
- libmemcached-1.0/memcached.h
+Libmemcached is layed out by interface version. The 1.0 version would be found in: libmemcached-1.0/memcached.h
The historic libmemcached/memcached.h includes libmemcached-1.0/memcached.h. For best practice you should include the version of libmemcacached that you used during development.
