 * This version has all the functionality (since it is derived from) of
 * TIniFile.  It has been modified to have the following additional
 * features:
 *
 *   Search the entire .INI file for an item.
 *   Replace an item in a .INI file.
 *   Delete an item from a .INI file.
 *   Add an item in a .INI file.
 *
 * These four features are notable in that they will work with SYSTEM.INI.
 * The [386Enh] section of SYSTEM.INI contains multiple lines of the form:
 *
 *   device=...
 *
 * These lines mess up the normally used Windows functions
 * GetPrivateProfileString and WritePrivateProfileString since they are
 * looking for unique identifiers. Since the ReadString and WriteString
 * methods of TIniFile are based on those functions they mess up too.
 *
 * The methods to add, delete, and replace .INI file items accomplish there
 * actions by making copies of the file.  This means that your directory will
 * have back copies of the .INI file you modify.  It is up to you to decide if
 * you want to clean these up or leave them around.
 *
 * I wrote this to go along with TInstall from Bill White.  Our application
 * must have a .386 VXD installed to work correctly.  Every .INI component
 * I looked at did not handle the wierdness of SYSTEM.INI.  So here it is...
