    <title>Introduction to unixODBC</title>

    <para>
      The <application>unixODBC</application> package is an Open Source
      ODBC (Open DataBase Connectivity) sub-system and an ODBC SDK for Linux, Mac
      OSX, and UNIX. ODBC is an open specification for providing application
      developers with a predictable API with which to access data sources. Data
      sources include optional SQL Servers and any data source with an ODBC Driver.
      <application>unixODBC</application> contains the following components used
      to assist with the manipulation of ODBC data sources: a driver manager, an
      installer library and command line tool, command line tools to help install
      a driver and work with SQL, drivers and driver setup libraries.

    <sect3><title>Configuration Information</title>

      <para>
        The files in <filename class='directory'>/etc/unixODBC</filename>
        are meant to be configured by the system administrator (or the ODBC site
        administrator if appropriate privileges are granted to
        <filename class='directory'>/etc/unixODBC</filename>). These files
        are not meant to be directly edited. The ODBC installer library is
        responsible for reading and writing the
        <application>unixODBC</application> config files.
      </para>

      <para>
        Unfortunately, there are not many <command>man</command>, or any
        <command>info</command> pages for the various programs available in the
        <application>unixODBC</application> package. Along with the information
        in the <quote>Short Descriptions</quote> below and the documentation
        installed in <filename
        class='directory'>/usr/share/doc/unixODBC-&unixodbc-version;</filename>,
        there are many <filename>README</filename> files throughout the source
        tree where the use and functionality of the programs can be found.
        Additionally, you can use the parameter <option>-?</option> for syntax
        and usage information. Lastly, the <application>unixODBC</application>
        web site at <ulink url="http://www.unixodbc.org/"/> has very good
        information.
