+= libcdb-ruby - Ruby bindings for CDB Constant Databases.
+
+== VERSION
+
+This documentation refers to libcdb-ruby version 0.0.1
+
+
+== DESCRIPTION
+
+The libcdb-ruby library provides Ruby bindings for the
+TinyCDB[http://corpit.ru/mjt/tinycdb.html] package for
+creating and reading {constant databases}[http://cr.yp.to/cdb.html].
+
+  require 'libcdb'
+
+  # creating
+  LibCDB::CDB.open('foo.cdb', 'w') { |cdb|
+    cdb['a'] = 'one'
+    cdb['b'] = '123'
+  }
+
+  # reading
+  LibCDB::CDB.open('foo.cdb') { |cdb|
+    cdb['a']  #=> "one"
+    cdb['b']  #=> "123"
+    cdb['c']  #=> nil
+  }
+
+  # hybrid
+  LibCDB::CDB.open('foo.cdb', 'w+') { |cdb|
+    cdb['a'] = 'one'
+    cdb['b'] = '123'
+
+    cdb['a']  #=> "one"
+    cdb['b']  #=> "123"
+    cdb['c']  #=> nil
+
+    cdb['a'] = 'two'
+    cdb['c'] = 'xyz'
+
+    cdb['a']  #=> "two"
+    cdb['b']  #=> nil
+    cdb['c']  #=> "xyz"
+  }
+
+  # update existing database
+  LibCDB::CDB.open('foo.cdb', 'r+') { |cdb|
+    cdb.store(cdb.to_h)
+
+    cdb['d'] = '42'
+
+    cdb['a']  #=> "two"
+    cdb['b']  #=> nil
+    cdb['c']  #=> "xyz"
