- * Document-class: SDBM
- *
- * SDBM provides a simple file-based key-value store, which can only store
- * String keys and values.
- *
- * Note that Ruby comes with the source code for SDBM, while the DBM and GDBM
- * standard libraries rely on external libraries and headers.
- *
- * === Examples
- *
- * Insert values:
- *
- * require 'sdbm'
- *
- * SDBM.open 'my_database' do |db|
- * db['apple'] = 'fruit'
- * db['pear'] = 'fruit'
- * db['carrot'] = 'vegetable'
- * db['tomato'] = 'vegetable'
- * end
- *
- * Bulk update:
- *
- * require 'sdbm'
- *
- * SDBM.open 'my_database' do |db|
- * db.update('peach' => 'fruit', 'tomato' => 'fruit')
- * end
- *
- * Retrieve values:
- *
- * require 'sdbm'
- *
- * SDBM.open 'my_database' do |db|
- * db.each do |key, value|
- * puts "Key: #{key}, Value: #{value}"
- * end
- * end
- *
- * Outputs:
- *
- * Key: apple, Value: fruit
- * Key: pear, Value: fruit
- * Key: carrot, Value: vegetable
- * Key: peach, Value: fruit
- * Key: tomato, Value: fruit
