+   * A poor-man error facility.
+   *
+   * This code being written in vanilla C, doesn't have the luxury of a
+   * language-supported exception mechanism such as the one available in
+   * Java.  Instead, we are stuck with using error codes that must be
+   * carefully managed and preserved.  However, it is convenient for us to
+   * model our error mechanism on a Java-like exception mechanism.
+   * When we assign an error code we are thus `throwing' an error.
+   *
+   * The perservation of an error code is done by coding convention.
+   * Upon a function call if the error code is anything other than
+   * `FT_Err_Ok', which is guaranteed to be zero, we
+   * will return without altering that error.  This will allow the
+   * error to propogate and be handled at the appropriate location in
+   * the code.
+   *
+   * This allows a style of code where the error code is initialized
+   * up front and a block of calls are made with the error code only
+   * being checked after the block.  If a new error occurs, the original
+   * error will be preserved and a functional no-op should result in any
+   * subsequent function that has an initial error code not equal to
+   * `FT_Err_Ok'.
+   *
+   * Errors are encoded by calling the `FT_THROW' macro.  For example,
+   *
+   * {
+   *   FT_Error  e;
+   *
+   *
+   *   ...
+   *   e = FT_THROW( Out_Of_Memory );
+   * }
