- * Document-class: GDBM
- *
- * == Summary
- *
- * Ruby extension for GNU dbm (gdbm) -- a simple database engine for storing
- * key-value pairs on disk.
- *
- * == Description
- *
- * GNU dbm is a library for simple databases. A database is a file that stores
- * key-value pairs. Gdbm allows the user to store, retrieve, and delete data by
- * key. It furthermore allows a non-sorted traversal of all key-value pairs.
- * A gdbm database thus provides the same functionality as a hash. As
- * with objects of the Hash class, elements can be accessed with <tt>[]</tt>.
- * Furthermore, GDBM mixes in the Enumerable module, thus providing convenient
- * methods such as #find, #collect, #map, etc.
- *
- * A process is allowed to open several different databases at the same time.
- * A process can open a database as a "reader" or a "writer". Whereas a reader
- * has only read-access to the database, a writer has read- and write-access.
- * A database can be accessed either by any number of readers or by exactly one
- * writer at the same time.
- *
- * == Examples
- *
- * 1. Opening/creating a database, and filling it with some entries:
- *
- * require 'gdbm'
- *
- * gdbm = GDBM.new("fruitstore.db")
- * gdbm["ananas"] = "3"
- * gdbm["banana"] = "8"
- * gdbm["cranberry"] = "4909"
- * gdbm.close
- *
- * 2. Reading out a database:
- *
- * require 'gdbm'
- *
- * gdbm = GDBM.new("fruitstore.db")
- * gdbm.each_pair do |key, value|
- * print "#{key}: #{value}\n"
- * end
- * gdbm.close
- *
- * produces
- *
- * banana: 8
- * ananas: 3
- * cranberry: 4909
- *
