 * $Log: config-parser.c,v $
 * Revision 1.9.2.9  2007/03/14 19:18:08  chessing
 * Some patches that didn't get in last time because of conflicts.  Adding/changing some of the configuration file settings.  Because of this logging will be broken until I get a second to fix it. ;)
 *
 * Revision 1.9.2.8  2007/03/12 00:30:36  chessing
 * Some code cleanups, and fixes to make the Mac version build again.  The Linux version is going to need a little more work to get in sync.
 *
 * Revision 1.9.2.7  2007/03/10 00:51:08  chessing
 * Rewrote libxsupconfwrite library to generate the XML configuration format that is now in use.
 *
 * Revision 1.9.2.6  2007/01/29 18:45:12  chessing
 * Fix up some dependancies for libxsupconfig.
 *
 * Revision 1.9.2.5  2007/01/20 22:55:44  chessing
 * MASSIVE change of the configuration file to fit the new UI that is currently in development.  Has the added benefit that it makes it easier to reuse credentials in different networks without rewriting the config.   Will do a commit soon with updated examples.
 *
 * Revision 1.9.2.4  2006/12/29 19:28:17  chessing
 * Changes to bring Mac/Linux versions in sync with Windows work.
 *
 * Revision 1.9.2.3  2006/12/28 21:37:30  chessing
 * Added project files to build more libraries and tools in Xsupplicant /lib and /tools directories.
 *
 * Revision 1.9.2.2  2006/12/27 22:14:34  chessing
 * Changes to the VS2005 project files to build ntpwdhash now, and to build libxsupconfig as a library.
 *
 * Revision 1.9.2.1  2006/10/12 03:45:04  chessing
 * Huge update to replace the existing configuration file parser with a new XML based parser.  This means that older configuration files will need to be converted to the new format in order to be useful.  There should be an automated conversion tool shortly, at which time we will convert the example files in etc.
 *
 * Revision 1.9  2006/05/14 22:09:28  chessing
 * A few small changes in the Xsupplicant code.  Beginning of a configuration/monitor program can be found in gui_tools. (Very simple for now, with several known bugs, but no showstopper bugs know.)
 *
 * Revision 1.8  2005/11/16 02:18:39  chessing
 * Updates to the config writing library.  The config-parser tool has been modified to be able to parse a config, and rewrite it.
 *
 * Revision 1.7  2005/10/17 03:56:55  chessing
 * Updates to the libxsupconfig library.  It no longer relies on other source from the main tree, so it can be used safely in other code with problems.
 *
 * Revision 1.6  2004/10/22 05:11:03  chessing
 * Major changes to Xsupplicant. Xsupplicant now only works on a single interface, with a much more simplistic set of goals.  As a result, many configuration options have been removed.  For now, the options that have been removed will generate a warning letting users know that they need to update their config.  Following the next release, we can remove them completely.
 *
 * Revision 1.5  2004/10/10 06:13:27  chessing
 * Small fixups to early patches to make things work with the new driver= section in the config file.
 *
 * Revision 1.4  2004/10/09 22:44:04  chessing
 *
 * The beginnings of card/driver specific options needed to handle the differences in cards for roaming, and WPA.
 *
 * Revision 1.3  2003/12/19 23:19:11  npetroni
 * updated config code and test example. Fixed a couple things
 *   1. added new variables to globals:
 *      startup_command
 *      first_auth_command
 *      reauth_command
 *      auth_period
 *      held_period
 *      max_starts
 *      allow_interfaces
 *      deny_ineterfaces
 *
 *   2. added new variables to network:
 *      dest_mac
 *
 *   3. added new variables to ttls:
 *      phase2_type
 *
 *   4. added new variables to peap:
 *      allow_types
 *
 *   5. layed the groundwork for "preferred types" to be sent in Nak
 *
 * Revision 1.2  2003/11/29 01:11:31  npetroni
 * Added first round of configuration code.
 * Structural Changes:
 *    added examle config file and finished config-parser to test configuration
 *    files and optionally dump the output
 *
 * Current Status:
 *   Have not added parameters for any other method than TLS so we can discuss
 *   the changes before doing so.
 *
 *   Did not update config_build() so chris can keep testing as before.
 *
 * Revision 1.1  2003/11/26 21:11:55  npetroni
 * Added a config parser directory in which to start writing a test parser.
 * no functionality yet.
 *
