/*! \class PIFile
 * \brief Local file
 *
 * \section  PIFile_sec0 Synopsis
 * This class provide access to local file. You can manipulate
 * binary content or use this class as text stream. To binary
 * access there are function \a read(), \a write(), and many
 * \a writeBinary() functions. For write variables to file in
 * their text representation threr are many "<<" operators.
 *
 * \section  PIFile_sec1 Position
 * Each opened file has a read/write position - logical position
 * in the file content you read from or you write to. You can
 * find out current position with function \a pos(). Function
 * \a seek(llong position) move position to position "position",
 * \a seekToBegin() move position to the begin of file,
 * \a seekToEnd() move position to the end of file.
